Matter Classification and Properties

So hi everyone I am yours Prashant Bhaiya, I have brought more science The next chapter of ninth class which is Matter around us is pure but why do I wear glasses I came wearing it just like this but you have it today With the help of many experiments, this I am going to explain the chapter, this chapter is very It seems too boring, doesn't it? Brother, I am unable to understand the collider solution What are suspensions? Brother, what is this Tyndall effect? Something happens, I am unable to understand it, I am unable to remember But I guarantee that today's lecture you don't need to remember me after there will be no need to remember You will understand all the definitions today, right? Whether you have understood me till today or not I don't know but you will understand this today Prashant Bhaiya there is a guarantee, before I told you I have already taught three chapters in class You can easily go to the playlist of Ninth Science you can see okay and if you read them then you must have understood at what level we are study the concept within less time I will ask important questions and here your school exam paper since then It's coming, this is my guarantee, okay You also tell your seniors Prashant says why to fear Bhaiya is here, okay then I am with you As long as I'm with you there's nothing to fear I will teach you so much that in a short time You will understand good things, you will understand the paper deeply I studied so much that I won't miss a single question. I will give you this guarantee, just give you the work This has to be done in its notes t gra or Then I will give those notes in the description You just have to read it once If you do it, your work will be done, your number will come full Let's go brother, let's start the first one My thing is that friend who are we inside this There are lots of topics that we are going to discuss It has topics such as Classification of matter, see, matter is what it is We had read that matter in the first chapter what would have happened yes tell me brother what would have been the matter tha anything that has mass and occupied baat That's right brother, I remember this very much in this country. Nice son, you know the matter Today we will learn about the same matter that The matter is pure, it is impure if it is pure so how is he if he is impor then how is he I will also read a lot of new things colloid solution etc etc etc Physical change is as important as chemical change in everything else. It is according to your latest syllabus If we were to read everything, we would start right away the first question I want to ask you is that is it brother what is pure what does the word mean like your home If brother comes inside, is there any milk then mummy says It's like my friend, pure milk is not coming to our house Isn't it pure milk, the milk that is coming is pure what does the word pure mean right, you can ask this brother if Milk is pure, it means that milk Our house is completely pure Is the milk I am getting pure? I will speak according to your mother So it is pure but according to science it is The definition of science is not pure, it is totally different Science says that that which is pure is not that you think it is different how is it different I want to explain, don't take tension, don't take tension but explain your energy level, your enthusiasm level before Keep the enthusiasm meter high and also your comments Divide your energy by 100 How much is the meter? Tell me quickly by commenting now. Also tell me in the chat because energy It is very important son, your energy will remain high The lecture will be fun, let's look at a table I will show you this table in detail. Today we are going to study in this chapter What is a table? If you look at it, you will see the matter. There are basically two types, firstly Here comes our pure one, there is pure and One is impure and the other is pure There happens to be one I will read about impurity but there are two pure ones too There are types of element compound elements There are three types of metals, nonmetals, metals and all I will read it in detail son, don't take tension and this Those which are important substances, we call them It is said that mixture is a mixture of two things. I will mix them, right? These are of two types Homogeneous and Heterogenous in Detail we will study there is nothing to worry about come on Where should I start, what do you say, pure? Starting with the substance, starting with the pure substance Let's start with the definition of chemistry Bhaiya what is pure in the definition of science It happens brother please tell me this to you I told mom that the milk is not pure friend When I felt bad, did my mother think that the milk is absolutely pure no no son it is pure there is no definition of pure, look it is pure Pure substances are defined as the substance that are made up of only one type of atom and one type of molecule which is one type of what do we call things that are made of We call them pure milk Son, a lot of things happen Calcium vitamins mean lots of there are molecules, right, so that means What if your milk is pure? No, it is not there bhaiya it is a scam it has happened What is pure? Pure is that thing which is pure made of types of things such as water why is it pure because brother water is a You should never consider water as chemical If you write it, then it is water, then it is h2o only Never let the water in your house turn into H2SO If the chemical doesn't come then only H2O comes. if h2so is coming into your house Son, something is wrong, you should be given acid if you remember then look you know water So the water remains pure, meaning it is a It is a substance, brother, how will we recognize it? Friend, am I pure? Am I a little pure? tell me something, give me some definition How do I recognize these two characteristics? I tell you about characteristic memory There is a simple way to do it which is What is CID brother CID Daya used to come break the door the same one CID no no no not that one, look at this There is a different CID, you just have to remember CID C is from Consistent Properties i.e. Of all the pure substances The properties are consistent i.e. same What is consistent? Continuous as in You are not able to study consistently You read for 2 minutes and then open your mobile phone You are not consistent but son, you are pure Joe They are substances that remain consistent How come their property remains the same property like yaar their biological Melting point Density Color Everything it stays there it doesn't change it doesn't change okay yes they are exactly the same what is the matter with i son i have inseparability be careful See what inseparability means Cannot be separated from physical medium Imagine you have water. what is h2o now i tell you this water of hydrogen separate me oxygen me Separate it and that too through some physical process I mean don't use chemistry, chemical don't use the process with physical process You pull the water and tell him that friend Hydrogen come to me oxygen come to me come, he will never come brother what are you saying You are saying this brother, it is not possible, that is the issue means to remember that the pure substances they are inseparable bye What is physical? By physical means any physical They cannot be separated from the process Let's see next what's next from D Definite composition means they have a definite and There is a uniform composition, isn't it? as you can see if you look at h2o Look, two hydrogens and one oxygen If it is combined then what is it, it is a composition that two hydrogens always connect to one oxygen it will never happen that four Hydrogen is combining with oxygen this can never happen it will always happen If there is a definite composition like this then We will remember CID whenever anyone asks us Brother, tell me the properties are pure If you ask for substance then tell them that CID work is over Let's move ahead and see now brother How many types of pure substances are there there are two types two types who There are two types of it, first is our element and What is the second compound element? There is an element in life like you, son He is all alone, he has no one else The poor guy is alone, how do we see the elements which is element is basic form of matter that can't be broken down into simpler substances by chemical reaction element vo who is always alone and who is lonely No, son, no one can break it. Someone who is alone in life can't break him he can't because he has nothing to lose There is no similarity which is its own element It happens like suppose there is only iron now You can't break down iron any more Iron will always remain iron Cha iron koi tum break it like this and convert it into two pieces But iron will remain iron, iron will not change okay so what is the element An element is something that is a basic form is of matter that can never be broken All the elements are present, there is iron there is gold, there is silver, everything Whatever elements you have next Let's see what compounds are are compounds are basically two or two When more elements come together I meet him, what do we say look for compounds such as water in water Hydrogen is an element Oxygen is an element Both of them came together and what did they create, water means this What is this, is this our compound, another one like this I will give you an example, CO2, what is this even ours Understanding Compound Element Compound Different Phs It has arrived now and we will study the compound in detail but first of all about this element bhaiya let's pick them up and talk to them brother how are you yes brother how are you doing If it is going on in your life then let's go First of all let's look at the element There are basically three types of elements Which one is it? Our metal is one One has its own nonmetal and the other has its own metal hey everyone what are ids metals Do you know what you are saying brother? I have to tell you look if you are watching this periodic If you look at the table, remember the periodic table. No need to take many tuitions It is done by remembering inside but I do not remember It doesn't matter, yes in 11th I'll have to go and remember, but don't remember anything right now do it, it will work, what are metals like so you can see this is the whole line This whole line, what is this to you? Where are the metals and where are the nonmetals here but and what's in between is what it is metal ides so what are metals Basically metals have some properties right? how do we know if it is metal or nonmetal if I give you some I will give you this and ask you to tell me this is metal or non metal then how will you identify it so let's go Let us discuss some properties first Let us first look at the properties of the metal Property metal is luster as i.e. shiny Have you seen what iron is, it shines? There is a little bit of shine, silver shines it is gold it shines what is this is it is all metal Metal is shiny, mostly fine other than that metal conducts heat and The electricity wire that you have Son I was shocked I was shocked I know who made it What is Copper? Copper is a metal is great so what happens heat and conducts electricity through its Apart from this the metal has silver grey or gold Yellow colour or silver grey colour it happens like your run or the one which What colour is your yellow? The colour is yellow golden which means gold type the color is okay let's now look at three more most These three are important properties Properties are very important star Mark it, the question definitely comes from here The first property is male ability and the second is ductility and the third is our sonorous It's sonorous, isn't it? We have three main properties of metal which I call SDM Sub district is not an SDM There are magistrates who are your There would be a sub-magistrate of the district Similarly SDM can be remembered from SDM There are three major properties, what is the first one? sonorous what does sonorous mean The old fashioned one at your school There is a bull in our house, when I I used to go to school, a brother used to come and that ton ton ton ton ton ton, you used to say that ton ton ton is not it The metal makes a sound when struck gives a sound non metal does not give non what is metal what is nonmetal imagine Do carbon, if you kill carbon then you will kill carbon It will break, right? If it gives only metal, then or that is, metal always produces a ringing Ringing sound whenever you hit it makes it what we call sonorous okay Let's see next, next is our D ductility what is ductility it is the Property of a metal to get converted into wire means take a metal and put it into a convert it into a thin wire do we say what do we say to him Ductility comes last property our fair ability fair ability what There is a metal I took it and brought it hammer ok take the hammer of Thor I hit hard and hard and I cut it into thin sheets converted it if I did it what will happen, will it become his property What does Melbinability mean V Can Hammer Metals and Form It Into Thin Sheets i.e. property of metal to get Converted into thin sheets, you will remember SDM are the three major properties of Metal and these are only near metals nonmetal I do not give this property to anyone, no na na na na Nonmetals do not have any nonmetal among the three There is no property from any there is no property let's talk about non metal Let's talk about non-metal display Variety of colors: Many different colors There are nonmetals other than that they are poor Conductors do not conduct electricity to conduct heat to someone I don't do it brother, what else do you have other than that not luster sonorous mellable some of the three There is no example brother, what is carbon is there oxygen is there nitrogen what is all this what is this gas that you are seeing These are all your non-metals. Okay, now the last one. metal metal id is coming there is nothing see This metal, this nonmetal, the poor metal in the middle If the edge gets stuck, hold the metal edge with one hand Sometimes it is pulling non-metal and sometimes it is pulling metal Sometimes nonmetals show properties of Sometimes it is showing metal and sometimes non-metal Why am I doing this dance? I am fine what is metal id the element that having Intermediate properties between doses of metals and nonmetals are called metals id right here Till now it is clear, let's move ahead with the example What is the example of boron silicon Germanium is an example of this remember son let's move forward now come The compound is very important and the properties of the compound are really Very important, please mark double star The question will come in the paper and then you will speak Prashant Bhaiya leaked the paper I had already told you that this question was not asked it will come okay now listen what is the compound when We have combined two or more elements When they mixed together, they got a property They created something new which we what did we name what did we name compound okay now here's one thing you One must remember that a mistake in its definition is a mistake a child does see definition it is the Substance that consists of two or more Substances Chemical Combined Chemical Combined together in fixed proportion this is it This line, this line is very important, meaning When compounds are formed they are fixed are in proportion, meaning let's say two When those two elements meet, neither is it within a fixed proportion You will find that this element will come and these 2 grams You will get this element, it will come in four grams and together they will form a new compound made means there is a fixed proportion if If that proportion is not fixed then A compound will not always be formed, then You will get it when there is a fixed proportion I did not understand, please explain with an example We understand by example the water You can understand what I am saying by example I want to start with the example of water Look, everyone understands that water is a compound You know, now look at the water being formed Neither is there a unit, understand it carefully The mass of hydrogen is 1 If you don't know this yet don't worry Now go and study, just understand it, okay and oxygen has 16 ay ay so what happens two hydrogens come two Hydrogen comes, that means 2 ay come 2 ay come and there are 16 ay of oxygen i.e. The ratio becomes 1:8 whenever The mass ratio of hydrogen and oxygen is only then will water be formed if these fibres are a little If you imagine it moved even a little bit More oxygen has arrived, let's say it becomes 1:9 So water will never become a compound can Never be a form i.e. a fixed proportion There should be a fixed proportion if this doesn't happen then water will never form no compound will be able to form and The biggest property of the compound is that Always a compound in fixed proportion Now let's do something important Let's talk about properties The compound has three important properties Understand carefully what the first property is substances are chemically combined with each other In the fixed proportion I told you hey diya we do chemical combine right Chemicals combine well together I just want to ask you a question tell yourself imagine inside the chat imagine do I took water I took water and I opened the sugar inside it. I opened the sugar inside it, what do you think Guess what, now the compound has been formed It was not made, son, why was the compound not made? Because I did it through a chemical process I did not add it, I just added water to it I added sugar, what is this, a physical This is a process but when are the compounds formed? Some chemical processes are chemical When the process takes place, then compounds are formed so remember that's okay now look at the other What is the property? The second property is the Properties of compound are different from di it's conciet let me explain the meaning look big I am going to tell you an interesting thing Your brain will make such a noise that you will enjoy it Look at hydrogen in life which is hydrogen What are the properties of hydrogen? It is a more flammable gas i.e. hydrogen is not If hydrogen goes into nature then it will become very It explodes quickly, catches fire, right? What does oxygen do What is oxygen gas like oxygen which is a gas, if oxygen comes then The fire would increase more with oxygen, right? What increases, the fire increases more, right? But look what a game this whole nature is that when these two meet and when If we mix water then the work of water will be done What happens if the water extinguishes the fire? Meaning both of them say devil man butt When both of them came together, they became good men. Brother, you see what a good rule it is and This is the rule of compounding when a If a compound is formed then whatever two There are elements of both of them, right? the property vanishes and the compound It turns out they have a new property New property is formed and last let's see a come the component of the compound can only be separated by chemicals processes means if I now have a h2o If we want to separate hydrogen and oxygen then I can't do it through physical process Some chemical process would have to be applied, such as a Process takes place in electroline 10th You will go and read it, don't read it now, okay, I understood. You will remember these three points very much These three properties are more important let's remember the compound of the compound Let's move ahead quickly, I've told you this I have told you, now there is one more question in your mind. My question to you is classify the following into element compound and mixture quickly What is Sodium? Sodium is a type of metal so what is it hey son, this is the element should I apply it on this hai element ok son then there is soil soil what is soil what is soil Is soil a compound or a mixture? hey bhaiya what is this mixture So tell me first let's solve this question but before that you should do it once Let me tell you what this mixture is The thing is, we just read what is the element, brother we just read what a compound is, right But brother, what is that mixture, let's see first Brother, we will see the mixture and then this we will understand the story quickly Look at the mixture, what is the mixture mixture is an impure substance and ek tha pure There was one Impor who is Impor, what is that This is our mixture, can you understand what is import Our mixture is important, the mixture is fine Let's read the definition if two or more Substances and Elements Compounds R mixed together in any proportion any If we mix it in proportion and There was no chemical change in it If only a physical change happened then we would call it that what is the mixture what is the mixture means I I took water, sugar or salt gave got got got got got got diya what has become mixture has become mixture I took salt and mixed it in the water If you add soil then what will become of the mixture What is mixture, son? Mixture Basically look inside the mixture If you understand carefully, what was the compound A compound was two or more elements If chemicals are combined then a compound is created How to make mixture? There is no mixture in the mixture. There is no chemistry in the mixture There is no chemical compound, what are you doing in it we are taking two substances together I am adding some definite There is no proportion, we have to mix it somehow that brother take 40 grams and mix it with 50 grams Give it to me, mix it with 60 grams, isn't there any proportion no, we call it mixture now There is also a difference between mixture and compound I will tell you but first let us see what the mixture is How many types are there? There are two types of one is homogenous and one is this is hetero genus brother what is this homo What is hetero? Look, you can see it only through the word homo. It will be understood that there is a similar There will be particles and I will understand you in hetero It might be coming that there are different particles in it first let's read the definition then another Come on friend, I will do a small experiment as well Let's see, first of all you need to understand very The more important thing is to look at What are homogenous components components are uniformly mixed with no visible Boundaries means when I mixed sugar in water When I mixed sugar in water, it became completely If you get it then can you see it where is the sugar in the water Where is it, I can't see it brother, I can't see it If possible, then that mixture in which all the methods are Even mixing becomes even It is mixing, what do we call it We call it Homogeneous Hetzner what it happens that the compounds are not uniformly mixed If I take some soil and mix it with water, You will not find soil, you will not find it in water He will get it, he will not get the uniform What shall we call him? We shall call him hetero Janas Mixture let's try it once We'll try it once and see it should be brought quickly it should be brought in one minute Bring the sugar in a minute quickly, here it is Brother, here is the sugar in my hand I am a glass now this glass that one It's not the glass you're thinking of, son. look this is sugar this is sugar and now I I am going to meet you, can you see me son? The sugar is white in colour, yes it is very fine sugar Now I added a lot of sugar It's too much but you will get it when it's complete what if all the sugar gets mixed inside it It might be that I have added a bit more sugar now I have just posted it so it seems to me that this then the ground will come down but okay so that means you Do you understand that when I add this sugar what will happen if I turn it around completely what will it do completely inside it you will get it and when it is completely If I get it inside then should I do it separately? where is the sugar where is the water I can't understand you, understand what I'm saying What is a homogenous mixture in which We did not separate the different things we can mix it so that it gets mixed evenly Let's go, I have brought some sugar for you friend I brought it after asking mom from mom Mummy wants to make the kids do an experiment Friend, give me that sugar, at least one friend Tell me something, this happens to you too does this mommy have a super Power, today I had to wear a shirt, right video So I said I went looking for it I can't find my shirt, then I said mom Mummy called out where is my shirt? I can't find it, mom said it is there I said hey where am I looking at that for so long and then mummy comes threat that if I come and get it then Now friend we get so scared again and again Let's see, then you get angry, right? I have looked anywhere, you don't know everywhere Where do you keep my stuff then mom? she comes and these are the clothes, Tell yourself that you are playing a game with yourself they are no longer there they hide and as soon as When mom comes these clothes come out Mummy came and asked me which shirt I wanted I said it is black and blue in colour, I want that Mom took this out, oh what is this brother how did this happen, it happens like this Friend, I don't know what scene moms are thinking I don't know how I know, but yes I brought it from my mom, what was this? If it was our homogeneous then you should understand it to be homogeneous Components are uniformly mixed with no Visible Boundaries There were no boundaries I can't tell if I had water I dissolved the sugar, son, then after that We can't find where brother Chinese is where is the water ok what else is there The particles are uniform Distributors go can't be separated by physical means now if I If I mix sugar in water then I will physically I can remove the chemicals by any means but Physically I do not consume sugar and other raw materials through any process. cannot separate water, sugar and can't separate water what's next the The ratio of the composition can vary no matter how much Should I add sugar? No matter how much salt I add It doesn't matter, nothing is fixed There is no proportion, now let's talk about us About Hetero Janus Mixture Hetero what is janus mixture like if you If you put soil in water then what will it be He becomes a son, he becomes one type I will also give you a Hetero Genetic Mixture I will show you a minute, please give me one minute I will show you how to do this as well, now see As if this is the same glass inside which the sugar has been added okay now you can see yes there is no sugar in it but what is this I have come to the lake, I have brought mud, son You see, I have brought sand Look, I'm bringing a sand wand for you now look at this if I mix this up Look carefully son, it is a glass hope you can see it i hope if you If I remove my fingers then it will be visible that this is this, this is soil this is this, this is soil You must be able to see its particles You see, this is soil, if I put it Even if I mix it I won't get this and this soil It will settle down like this again and again if Even if I try to find it I won't find it and this See what will happen when you go down, it will settle down Again and again through this experiment I have told you What did you want to tell me that this was our heterosexual mixture look inside hetero genus mixture What happens if the compounds are not uniform mixed or not formally mixed and what happens inside it what happens inside it we can separate we can see that Here is the water, here is the soil, here is the water Here is the soil, what else is there besides that can be separated by physical means if I If I filter the water If I remove it from the paper then the soil will remain separate And if water comes then it means from physical means water can be cleaned if not Physical Meaning of Hetero Genetic Mixtures can be cleaned and separated from okay so here are some examples of this the i hope you get heterogeneous homogeneous You must have understood about the mixture What is mixture has become clear Element Compound Mixture Now I first of all so I want to show you one thing what is the different between mixture and Compounds Between Compound and Mixture What's the difference because this is a huge the question is because look at the elements I I mixed two things to make a compound What is the difference between mixed and mixed mixture? There is a difference between properties, understand them carefully Understand carefully what is the first property Formed by physical mixing to and more How is the substance mixture being obtained physically I am mixing it but how is the compound being made is chemically bound compound How is the chemical combine being made? okay what's next this is this one type of import substance it is a type of pure substance it contains What is the composition of the mixture it happens ... How much sugar should I mix with any amount of soil? It doesn't matter if I get it but there is a difference here happens right when a compound is being formed So the next one is made in fixed proportion what can be homogenous and heterogeneous But what compounds will always be homogenous Remember that compounds will always be homogeneous As water is homogenous, let's see further can be separated by physical means this also Your mixture is from physical means I just told you we can separate them, but not this Maybe compounds can never be separated Remember next we will see concedes written their individual properties i.e. look if If I mix sugar in water then the quantity of sugar Chinese property will not be taken away What is the property of sweetening the water? If she makes me sweet then it means someone in the property There was no change but when I added hydrogen when water is mixed with oxygen I made hydrogen and oxygen That the properties of both of them had changed, right? no and water have a different property then That is, the properties that are present in the compound It changes but when we make a mixture then no property changes okay Then no property changes, do not do it have defined melting and boiling point Their boiling point would be their melting point it is absolutely fixed okay and What's Next No New Substance R Form All these properties depend on the context Things I've told you that concieve The property remains the same but here it is different it happens okay so this is the table It will come in your paper very quickly. You can also note this table because This is a very important table, you too much for everyone It is important to move forward, let's move forward This is our mixture and compound Now I want to show you the same table. tell me which are the mixtures are the elements and which compounds are quickly tell me which ones are these First of all let me tell you that it is sodium Why an element because sodium is a metal yes very good next is soil soil what hey what is soil brother it's a mixture There are a lot of things in soil This is the mixture sugar solution I just made Showed what is this mixture which is homogenous mixture What is silver? It is a type of metal. What is the element calcium carbonate contains calcium carbonate caco3 this is a type of chemical compound when bound then this is what happens Let's move on to our compound, i.e. tin What is tin, it is a type of metal, so its also You can write this is also an element silicone what is silicone son silicone is a If it is a type of metal then it is also an element What is coal? Coal is mixture coal There are lots of things inside carbon and many other things happen, coal is one Air is a mixture and soap is also a mixture methane is a mixture what is methane methane is a what type of methane is it compound carbon dioxide compound blood What is mixture of blood and many other things? hoti hai blood is a type of mixture theek hai I have understood the element element compound Mixer, if you get such questions then what will you say? You will tell me, won't you? You will tell me, brother. What a great thing brother, they come like this and Simple questions come to mind, you can answer them easily You will find that you are enjoying it too, now tell me how do you feel I am enjoying it, I am understanding it and do you understand with that And if you are able to understand deeply then there is something Now let's move ahead, a question comes up and these questions are asked again and again in the question paper R Alloy has come inside many schools What are mixed mixtures and compound alloys Brother, I do not know this, let me tell you I will give you what they are in your house Copper utensils are brass utensils Some houses have brass houses yes it is there so what is brass brass is a type is an alloy of If you are getting Alayil then you are getting elements whenever two elements meet you have I had told you brother that compound is made but here Compound is not formed here, it is called mixture we are aloy knows why aloy Why do you say mixture? Question repeatedly? I have been asked, I will let you know Because look, there are only one or two reasons for this The first reason you should understand is because they are written there Properties of Conceit elements suppose i took i took I took copper, I took zinc, I took both I mixed it up and I made a new alloy Now whatever alloy comes, it will have copper in it Zinc properties will also be properties and when the concit element is what do we become when we have property what do you say then it is a mixture like I mixed sugar in water and the water There was also property, it was Chinese property The property of sugar did not change after getting it It is later when the property of the concedes If it does not change then what do we say then we That's why it's called a mixture Aloy Alloys are confused about which alloys are compounds because the alloy is physically can't be separated if I have a If I made an alloy then I would not do any physical change can't separate them both with help But the metals are still an alloy mixture because inside it the properties of concets It remains the same, it remains the same and another region there is another region its son, there is no one in it There is no fixed proportion such as value take h2o when we made water We kept a fixed amount of hydrogen and oxygen One kept fixed of both kept fixed of But brother, nothing gets fixed here. Here they say no matter how much percentage you take take it 20 30 40 like when we get brass If you want to make it in brass then we will make it around 30 rupees If you take zinc around and copper at 70 then Even if it is up and down, it still becomes an alloy If it goes then it means there is a fixed proportion There is no other Conceit Ants properties It remains very good son very good Let's move ahead, now see the mixture I have made I told you about Homogeneous Hetero Genus now Let's read a little more in detail, go ahead Look, now my next question comes, friend What do we call a homogenous mixture which It is a homogeneous mixture, right? Let us tell you what the solutions say The solution is exactly as I said with water I added sugar inside so what did I make I have made a sugar solution, right? If you create a solution then that is the solution When do we tell you about the solution When the nature of the particle is, the particle is The size is very small, we have used it in water Sugar was mixed inside, the size of sugar is so small Whenever the size of the particle is very much smaller when we say what we say When we say that a solution has become a The solution was found but when I put the soil The size of the soil mixed was big The size of the particles was bigger when I If large particles are mixed properly Do you know what happens when you can't find it? What is a suspension made of? What is a suspension made of? When I mixed sand with water I did not find it, do you remember? Yes, I was in that what should I say it became a suspension suspension what happens is that it is a solution type of solution in which the particle size It is very big what is the particle size Larger than 100 nanometers means nano what happens son 10 to power - 9 ok what will happen if the nanometer is bigger than that Suspension Agar Agar Agar Particle Size in It is in between the two, in the middle means 10 ray to power - 9 to 10 ray to power -7 meter if If it is in between these two, what will it make? He makes collider solution example What is the example of collider solution? keep it, imagine I have some milk I took the milk and put the milk in the water you mixed it in a glass of water I have seen that the colour of water also turns white try doing it like milk, today it is there which The solution gets formed, because look, the milk which It happens but it is not fully available It is in the water, it is found unevenly It is available in water completely, isn't it? I don't get it, I get it little by little It turns the water white in colour so we call it What do we call it? We call it collider. What does the solution say beta collider Remember the solution is of three types The first solution is this one type of homogenous mixture in which What happens if the particle size is very small hey nanna munna like sugar is one Very large particle sizes, such as our stand soil is fine we call it There is a suspension and there is a colliding The solution that is in between these two is fine As if I got the milk, these three now we have to study these three things Many questions on each one of these in detail They come, then I will tell you a lot about them questions come okay so what you are doing now are you busy chatting son Come out a little, right? Otherwise, you are not able to come out. If you remain then listen to that line that the heart said this It is from the heart, the heart has said this from the heart yours is getting cut again come on brother this this Keep getting motivated by listening to the line again and again You will exit the chat or else you will not be able to chat I'm busy eating all the time whether it was there or not, you keep doing all that Come on, let's read the solution quickly If you look at the solution, look at the solution consists of two parts one is solute one the solvent was water and there was a what did I have I had sugar So what is water? Water is a solvent. Water What is water? It is the solvent, i.e. the component that Components are components that are connected to other We will mix the component inside us They say solvent water what is solvent and what was the sugar which was in very small quantity I was in it and what I found inside the water what is it we call it solute remember keep what is called solute the component that is are Remember the dissolution which is in small quantity That would be my solute in large quantity I have that it's gonna be my solvent okay It is in large quantity, like excess water There was a little sugar in the quantity what happened to sugar solute what happened solvent okay so solute and solvent You must be absolutely clear now I will tell you Let me tell you what these two make when combined These two are mixed together to make a solution That means if I have taken 100 g of water 100 g solvent taken 100 g water I took sugar 5 grams 5 grams So now tell me what is my overall solution how much did he weigh he weighed 100+ 5 means 105 grams, did you understand, right? Solute and Do solvents mix to form a solution? Now I told you this because Now we have to do some numericals. Some numerical questions have to be done first Let's see the identification Alcohol with water means if I drink 80% If I take alcohol and 20 litres of water then who will do it? Who is solute and who is solvent tell me who who is the solvent hey brother who More the solvent, less the solute the water that's inside this case of this case what will happen to the solute because it is less and what will happen if alcohol becomes a very solvent nice son very nice, did you understand Come on brother let's go ahead and see something now Before understanding numerical we need to know some You will have to understand the terms, there are some terms Don't think that the first term is concentration Concentration is concentration power right? Like you can concentrate on your studies I will ask you today about your concentration. What is power, how do you define it? Will you tell me to read without getting distracted? I call this ability concentration You will say this without getting distracted What is the concentration of similar solutions? depends on how much solute is put inside it when I added sugar to the water I mixed it, I would have mixed it for a while you would have got it like I showed you she has already found it inside her but if I kept adding sugar again and again so at one time This happens when there is more sugar in that water I can't find it, that is, what is it his concentration is his concentration concentration on it sugar on it I cannot mix water, he just says I That's all the sugar could have been added to it If I cannot mix it then what should be the concentration What is the concentration of a solution? of solute present in the given amount of is the solution ok how much solute It is present inside that solution, we They tell me what his concentration is I understood the concentration, hope this It must be clear now let's take it out brother would have taken out the concentration there are different solutions let us So I am not able to concentrate on my studies Let's find out the concentration of the solutions. Come on Look, there are some formulas and they are very simple You will enjoy the numericals You will say friend brother wow brother wow wow Prashant bhaiya wow you will say this from your heart The sound will be very simple, there are some formulas The first formula is mass by mass look It depends on the question now I will show you in the question if The question is whose mass have you been given The mass of the solute is given and the mass of the solute given is the solution of which solution is this no and you should be told find the concentration so what formula will you use Mass of solute by mass of solution * 100 because for percentage you have to make it 100 It falls in the question, right? You have mass given in the question imagine the solution is another question In which you will find mass of salute given is the mass of solute given is but What is the volume of the solution given to you? It is given volume, do you understand volume? How much water is there, volume is given, then which one If you apply formula then you will apply formula mass of solute by volume of solution * 100 okay and if any other numerical comes in which you have given the volume of whose of solute and volume given is solution So which formula will you apply Babu Bhaiya Solution: Which formula will you use? Volume of solute divided by volume of Solution * 100 so formula depends what type of numerical is it given to us The type of numerical that will be given is three We will paste even one from the formula and get the answer Let's solve the question quickly let's look at it and solve it We will talk about solubility later. we will ask the question first come brother see what the question is then make it saturated The solution contains 36 g of sodium chloride Dissolved in 100 grams of water at 293 Kelvin Find the Concentration at This What is the temperature and concentration saying I have to find out a formula for concentration I know if I am given mass then mass I will apply the formula that brother mass of solute divided by mass of Mass of solution in 100 IU I will remove it from the formula, right? The problem with this is that I don't know it look what is the solute sodium chloride because this is less so this is solute so salute and see what given it is No disoldering trick means remember one thing keep it because you will make mistakes in the formula The mass of the solution inside is counted how to find out the mass of solute plus mass of solvent so that means this and add this, add these two then If life becomes absolutely Jingalaala then one Now let's add the times 100 + 36 = 136 g That means the mass of solution is 136 g and what is the mass of solute 36 g and that's it Apply the formula, the final answer will be 36 / 136 * 100 Now you just solve this And tell me the answer in the comments, solve it What is the need to do basic maths now? This is basic math, now you can do it ok so this type of questions come Let's do one more question, if you understand It doesn't matter if you couldn't come next I see the questions again and again and again A lot of questions are asked too, aren't they? are asked in all schools also if there are CBSE linked schools Your school is also CBSE school There are many CBSE affiliated schools All of them are our KV etc. so in all of them It is asked, isn't it, and it is asked again and again It has been asked in many papers Here is a solution containing 60 grams of sugar in 480 g of water calculate the concentration of solution in the terms of how to calculate mass by mass percentage concentration mass of solute which is 60 grams and look what is this this is your mass of solvent so remember to add these two If you don't add it then you know what will happen I will go with you I will go with you If it becomes mine then what will be the addition of 60 g divide by 480 + 60 g then int 100 Brother, please put it in these too, who will put 100 in these? If you put 100 then you will get your month off solute divided by mass of solution mass I understood the solution, why am I taking it I am 540*100, so okay friend, that's it now Now what is it, we will calculate it now So there shouldn't be any problem with that Nobody has any problem now, right? If it is ok then how much will it come from zero If 1/9 is deducted then it will be 100/9 So this will be coming 100/9 percentage 100/9 Now calculate the percentage ok done this is what is coming for everyone Very good, so this is how we can ask questions You are looking at it in such a short time How many easy questions come There is numerical in chemistry too but a lot It is simple numerical, not like physics There is a physics of physics I read you If you have kept it then you have to see the rest next Which chapter do you want, you can also tell me that Do tell me in the comment, okay, let's go now Let's move ahead and now we have another question Let's see and this question is very good If this is a question from NCERT then answer this question Let me also look at this once so that you can understand more It will come and you will be able to see in detail Prajna tested solubility is one My name is always there in NCERT books Brother writes justice for girls Boys don't write boys' names yaar bhaiya Pragya betrays us Tested solubility of three different substances at different temperatures and collected the data as given below very good So he did different experiments at different temperatures. Count the solubility but bhaiya You haven't even read about solubility If the question comes first then first friend Let's understand the solubility friend, otherwise There will be trouble, you will say, brother friend Tell me the solubility, look at the solubility Did you understand what concentration is? How much solute is present in the solvent That is my concentration solubility what is the solubility is such that the solubility Suppose you have the strength to fight with me my strength i can probably beat a kid Now if someone comes, he is a 100 kg wrestler He has fought with me, he will defeat me Neither do I mean my power to defeat one with my claws if it is there then what is it, it is my strength That is my ability, every solution is similar has a solubility of means what is this it is the ability how many keep the solution inside you How much solute in dissolution The solubility of dissolution is due to this It can't be much, this was the last one This is the stage, a lot of salt should be added it should be poured after some time with that water salt cannot be added inside so the one which There is a time after which there is no salt in water could be mixed, that was its solubility So let's look at the definition of solubility a solute in a solvent at specific Temperature refers to the start from here do the maximum amount of solute that can Disoldering [music] Now I have mixed sugar in the water and I am unable to find sugar and if I should I change the temperature if I raise the temperature what will happen if I give it to you think about it previous chapter It is linked to I'll tell you, imagine You two people are standing there, right, one is like this Both of them are standing very close to each other It's okay nearby, now a person is coming like this And he tries to get in between you. He's coming, oh my friend, little by little There is some space brother, move a little to the side friend Go a little here, go a little here, a little there I am trying too hard but there is no space brother oh Go away friend, this is no place at all There is no room for particles at all They are saying they don't have space for sugar The particle should go away from here, there is no space Both of them are standing there is no space now Imagine, I should raise the temperature What happens if I increase the temperature increases kinetic energy remember last Chapter kinetic energy increases so now What happened? Earlier you were standing, your energy increased. now you have started to move now you have started to move Now the person next to him also started moving also started to move, so as soon as the particles When things move, the beach a space is created in me a space is created then Come on brother, here it is, there is another one in the middle For example, if you are from a middle class family yes, if you are like me then you saw me in your childhood that would happen if you were somewhere in the car If you are traveling then travel in a small car There used to be five to six people, now Suppose three or four people are sitting together, now one If people wanted to get more angry then how were you sitting He was sitting so that he could move a little forward and backward Friend, adjust it by moving a little forward and backward like this You used to sit only when there was movement When the kinetic energy increases, then When things come in, should I say anything? if I turn up the temperature My solubility will also increase yes or no, I understood why because As kinetic energy increases, so does solubility If it has happened then if I don't get my sugar If I can heat the water and After that I will add sugar, mix sugar comfortably You will go and try it and see Solubility can be increased by increasing the temperature I hope this concept is really good You must have got it absolutely clear solubility at that temperature What is the effect of solubility? Now let's see a table, you will understand from that also. let's say there are some compounds these are some compounds and their solubility If you have written about them then you can know about their solubility. See, as the temperature is increasing, you Look at the temperature and also their solubility First 21 and then the temperature is increasing When it increased it became 32, then 62, then 106 it has become 167 means as our Temperature is increasing, solubility is also increasing I hope this question is clear now, it is increasing This happens brother if the temperature goes down If the temperature decreases then the solubility Yes, if you accept the temperature now, it will decrease Now the particles are moving a little bit were moving a little bit, okay Now as soon as the temperature goes down If the kinetic energy decreases completely the particles will stop and as the particles What will happen if he stops and doesn't let anyone in? I will not ignite any particle If it cannot be found inside them then solubility it gets completely finished if we remove the water completely Cools someone down by putting them inside cold water Things cannot be mixed no matter how much you try try it out okay so this is a table which I am also telling you how Some tips on how to increase your solubility There were questions, look at those questions once It is a very simple question, it requires some brain Do not apply what mass of potassium Nitrate wood may be needed to produce saturated solution of potassium nitrate Look at these 50 grams of water at 313 Kelvin the question is saying that the question is saying that if you look at how much potassium we have How much potassium do we need for nitrate I need nitrate what is written produce the saturated solution the saturated solution How much nitrate do we need to make it Now what is this saturated solution you just told us that the solubility what happens but brother now you are saturated I did not tell you the solution, see when I If you mix sugar in water then after some time You cannot add more sugar to the water. That is the time after which there will be no more sugar Can be mixed and no solutions added You can go at that time, we will tell you that The solution is saturated meaning it is full It's full isn't it, as if I had never visited a bar I say that children's minds are saturated It's done, that means you were with Mr. L the whole day Are you running youtube4 shorts in your mind The information keeps increasing, the You are not able to study now, why don't you? because your mind is saturated The unsaturated solution has been filled What is the solution in which and The solute can be mixed by mixing you can mix it comfortably, now is the time right, then we call it unsaturated Saturated and unsaturated, their definitions too I'll show it to you later okay now what is it saying what mass of potassium Nitrate wood can be needed to produce a saturated solution of potassium nitrate in 50 g of water at 313 Kelvin table Let's look at that table itself. Look up potassium nitrate. Potassium look at nitrate and see 313 Kelvin which that right here it's 313 Kelvin on this What is the solubility of potassium nitrate is 62 g 62 g means that means what is solubility solubility Solubility once you remember the definition of I will explain it now by remembering the definition of What am I telling you about solubility Remember the definition and quickly find out where it went Where did a very important concept go? Tell me I have been thinking about the definition of solubility maximum amount of solute that can Disoldering Nitrates can be dissolved in that table This is what the table is telling us it is correct that in 100 g water there is 62 Gra in his okay what does this table tell us This table is telling us that it has arrived I understood it, I understood it, 62 now ask this question it is saying that if the water is only 50 g of water If there is only 50 grams then how much potassium Add nitrate if the water is 50 grams Brother, let me tell you, if only water If it is 50 grams then it is obvious that you don't say anything Do it if it is 62 in 100 g then what is the amount in 50 g Tell me yourself how much will it be if 100 g If I am getting 62 62 g in 50 g then You will get half of this, right? 31 for 50 grams Will I get grams, yes or no? Tell me yes or no. yes or no did I understand it, did I understand it this was the question this was the question that 50 How much potassium do we need in grams of water You will be able to mix nitrate at this temperature above I just had to do half of it, the amount was 31 To explain the meaning of solubility I brought a question for you To explain the definition of solubility I came with meaning and saturated and To explain the definition of unsaturated I brought it, let's saturate it once again Read the definition of unsaturated, I am a I should drink some water for a minute, just see it is unsaturated what is a solution saturated solution which does not contain any additional solute we can mix it bhaiya no and not solute We will match you, that one cannot happen now unsaturated in which we and solute we can meet come on son and move forward And now comes a very important topic which that is collider solution our solution is done In the solution done, we saw that there would be a solute is a solvent right now We are talking about collider solution It is very important that something comes into focus Go son, now this is a very important topic Look what is the collider solution Is it a type of heterogeneous mixture It happens like if I mix milk There are no small particles in the water If you come then whatever solution you get we call it that, do we call it that Does collider solution mean its particles a little bit older a little bit older and even there are no distributors It would be good if you remember our two solutions the parts were one the solute bhaiya was one Solvent Bhaiya, the name has changed here but the work is same Names have changed like Ram Shyam Shyam Ram name How did the names change? Names changed here. Disperse Face and Disperse Medium You must be understanding disperse from this Medium happens if I speak in the old language If I say so, this is the solvent and brother this is my dear nanna darling salute you Dispersion medium is that within which Disperse phased will come and get it means it this is salt this is salt so you will remember it whether there are two collider solutions parts what disperse face which is a Type of solute and disperse medium which is a type of solvent, it is clear It is clear, this thing has reached here It is clear who salutes who Solvent Let's now have a table and this table But a question always comes up and you assume that Come on, you will have to memorize this table because how will you remember this when you If you read it again and again, you will not remember it easily Son, it's a long table but you'll have to remember You will have to work hard my friend, you are the number one If you remember the number then do this also friend come Now let's look at the inside of this table. what is we've been given the disperse face and Dispersion medium is given in disperse face what would have happened son salute so this is our solute and this is our solvent so look son now look if I use solvent I'll get the gas to the place, what am I doing? What am I using instead of solvent? Gas And what did I find inside the gas I am mixing liquids, I have taken a lot of gas I put all the gas inside him a little What happens if you add a little water? what is an example its a cloud what is a cloud Lots of gas and a little bit of water What is the biggest example of this? Fog cloud and this type of mixture of There is a name for it, it's called aerosol Aerosol aero means the solution which is inside the air Aerosol can be formed in this way you can remember the air Ok solution, let's see next one now My solute is my solid and my gas is my Now I'll take lots of solvent gas gas and inside it little by little I will put a solid particle, what about it the exam is the smoke that comes out na smoke smoke The smoke that comes from the factory is gas what happens inside is very inside Carbon is a small particle etc. so what is that, that is an example of it If it exists then its name would also be aerosol But its example is smoke automobile I also remember the examples like exhaust etc. do I have to keep it and do I have to remember this name as well Why do you know how the question comes? The question will come. If we create a collider solution in which that we put a solid into a solid solid as a disperse face and our If you take disperse medium gas then what will that be? will create it and an example will come directly Or else the question will come back to you tell me what the cloud is What is disperse face and its disperse We should know what is medium What is a cloud? There is a lot of gas in the cloud. all and some liquid If there are droplets then I mean disperse Faced is liquid and disperse is medium gas let's go down let's go now that's it I am taking liquid solvent very much A little gas was found inside the whole liquid I have been an example, remember if I am very I'll take all the liquid and get some gas Your father must be using that shaving cream The shaving cream is like this There is a lot of gas inside the liquid which is the work of our shaving cream It does, okay, we call it foam what do you say son foam now see if I should I mix liquid inside the liquid of milk If I add water inside then what will happen? What happens to us then we remember What is emulsion called? It is called emulsion. You can take any example like milk in water what is the name emulsion move forward son If we move ahead quickly, we will see now solid now what did we do to convert solid into liquid I poured it in, which meant there was a lot of liquid, water There was a lot of it and there was little inside it a little bit a little bit liquid a little bit Tell me what happens if you add some solid What is it? Tell me quickly, one or two examples. think a lot of water a lot of water a little sa solid hey brother it is mud na mud mud There is a lot of mud like this brother We have a lot of liquid and put some soil in it If there are pieces of it then that is what mud is So we call it that, this is our name what is sol sol sol now if i take Lots of solids and a little bit of gas Should I put some gas in it, what then? When it is made my foam is made here as well I make foam and it is known to everyone What is a good example? I will give you an example. I will give you that, have you seen that sponge sponge I saw if there was a sponge here then I I hope I can show it to you too, it is not here no otherwise i would have shown you right now that the sponge What happens is that you suppress what you mean If the sponge has it then it is solid but its There is a little gas inside their pores so when we have a lot of solid What if we put a little gas inside the An example is its sponge next Let's see if I can get a lot of solids what should i put inside there is a lot of solid inside put a little liquid and a lot of solid Pour some liquid inside it, such as Our butter is cheese or not, what is butter Too many liquids or too many solids There is a little bit of liquid inside the butter Things etc. are its examples, we call it what do the jails say the jail goes on solid and solid oh solid and solid so some If it doesn't happen then it would be called our solid soul Say anything, one solid is another solid you will find me as if the stones were different Isn't it true that two stones come together solidly When two solid metals come together There are so many different things Yes, isn't it so we are an example in this Gemstones There are many gem stones there are different types of stones okay These whole tables were important to me I know it's hard to remember, but sometimes Any question may arise like imagine now tell me yourself now the question has come eraser Not rubber, consider it a sponge, the sponge has arrived What is Disperse Face Disperse Medium What do you think is the best sponge? What's more, there's a lot of it in the sponge There are gases filled in between the solids i.e. disperse phase is gas disperse medium it is solid let's take another example Let us take the example of soil, now let us move on to mud In the mud mud mud you will see that friend There is a lot of liquid in the mud and There are small solids, that is Dispersion medium is liquid and disperse The face is solid, such questions will come and You will do it because you have studied with us okay this type of question is very good Son, you will come inside the paper a little bit We have to be prepared before moving forward now we read what now we read Look at the suspension, son, what is suspension It is very important and the question also arises It is important to understand this chapter carefully It was very big at first but what happened after that This chapter has been made very short Those were your separation processes have been removed from the syllabus as of today I told you what suspension is remember the three types of Hetzner, remember the three What were the types, Bhaiya, what were they? Bhaiya there was one type inside us who What we used to do inside is make the solution homogeneous solution of two types of heterogeneous Bhaiya, what did we read? We read it the most First collider and bhaiya one was left suspension which were large particles, you I gave an example by mixing the soil Yes, you got caught in the water, my friend He has become smart by staying with me you are getting smarter yes very good Suspension see suspension is hetero people mixture in which solute particles do not disoldering I cannot find the particles right now, I will tell you I'll show you from the back Let me show you, look, this soil has been it was kept and this soil if you I will tell you If I come closer and show you, now if you see it then this Look, the soil has settled down like this Look, it is visible now, it is visible Now see how the soil is complete If it has settled, then the soil that is What is a type of suspension? You can see what is this a type of suspension Why is it so because its particles were found Not only this, its particles are completely If I don't get it then it is called mine Suspension ok read the definition again The solute particles inside do not dissolve but reman suspended suspended means sitting down they go away and stay the same like the soil underneath It settles down in the water, I understood it very well Very good son, now you can see the properties These are the properties of NCERT and the question is The properties of go under number three Tell me there is less chance of getting suspension but it would have come first thing is this is a heterogeneous mixture We all know this, the next thing is particles Are visible by naked ice i.e. one is naked what is dice eyes are nice What do we wear on our eyes? what does neck dice mean son without If you look at the microscope with normal eyes Even if you look without a microscope We will also see particles, see next Skaters light is very important right now We will talk about it in detail now Let's move ahead in detail about this we will talk son particle settle over time making it unstable particle settle down It goes very well Can Be Separated By Filtration If I filter the water it will be separated last point doesn't it Scatter Light is back to Scatter does not scatter light once particle settles Now this is another point, now a question is coming Brother, please tell me what is this scatter You are not half-incomplete things, everything is half-incomplete I will tell you, be patient, I will tell you everything and such I can say with confidence that I will teach you Whatever I teach appears in the paper Why does it come because research takes so much We have been teaching for years, we know what we know now listen to me what is scattering You will have to understand that scattering happens Imagine the spread of light Imagine, I will see you practically I will try to do it too To explain it to you, look at this, assume that the water it's a glass it's a glass okay its Now I put particles inside whose Add particles to collider solution or else Why suspension because their There are particles, son, there are many of them They are big, aren't they, which is true? The solution is normal, you can find it Its particles go but these two if these were not found then their particles which would have been they are like this aren't they, they are like this now here a light came from here a light came now light The light was coming straight to him, now he I got goons in the particle so when the goons what will happen if we meet i am going this way I have gone there, the light is running here and there So that means what will the light be, the light will spread a bit The light will spread like this The light will spread like this The light goes away, it spreads out, and then the light After that, if it comes out then it means that this The light is spreading, isn't it? This is what we call it What is Scattering of Light Scattering Scattering of light is basically the spreading of light go due to particles because light comes I was thinking now she got the particles friend right When she was coming from a normal solution, suppose If there is sugar water then nothing happens then the light will turn on Light laughed and said hey friend I had fun, there was no problem in life I came comfortably but as soon as it happened Muddy water came and there was a problem with the electricity Brother, there is some problem with the light, isn't it? the light got scattered, what happened, it got scattered I hope you understand the scattering process You must have understood that scattering of light What happens to this scattering now that I have I told you this because there is an effect which that there is the Tyndall effect and again and again the paper Inside it is asked what is tindal What is the Tyndall effect? Let us read the definition of Tyndall effect again Let me explain to you the phenomenon of scattering of Beam of light by collider particles when Passed and you know add it near collider This also happens due to suspension, right? there are suspension particles, aren't there? Even from the suspension solution The tendle effect phenomenon occurs Scattering of beam of light by collider particles and suspension when passed through Collider Solution is Called Tyndall Effect So what is the Tyndall effect, brother? Do you understand anything? He did not come brother, he just went over my head A little easier, hey I am in tension, listen to the note When, suppose there is one glass, from it I pass the light when I looked through that glass If you pass the light then there is water in it There is a solution in it, the true solution is sugar if there is a solution then the light passed straight but when does it contain colloid solution or Suspension is fine either of these If the solution has larger particles, then when I'll pass it through the water Do you know what will happen if the light is its path the path of the light will appear as if you If you can see this then you have to see this True solution: If you look at this, you will find the path I can't see the light just went out in it look from light light light light light What is visible faintly? The path is visible and it is even more visible from the suspension There has been more of the suspension If a clear path is visible then it means Tyndall There is no effect, this is the Tyndall effect that when a light travels the light scatters and if the light is scattered then it his path is visible to his own path We can see the way, we can know it well the light is going from here just to that They say it is Tyndall effect, right? Read the definition once and you will understand. The Phenomena of Scattering of Beam of Light by collider particle when pass through out Collider solution i.e. scattered light scattered as she was passing and her We could see the path we were taking When we found out about it, we gave it a name. did we name it colloid son The solution came and I understood it, tell me friend, what is it now? let's try it once let's try it once Let's try it once and see Can we carry out this experiment today? You can get it done here but I need it for that the lights will have to be extinguished and the lights I am just afraid of getting caught, I am afraid, Look, now the soil has settled down in it okay now I will extinguish the lights but I'm afraid give me a minute give a minute just look it is visible it is visible it is visible Now look what's inside Particles are good I will try it in a minute I try to extinguish the light You will understand it more clearly through that, just give it a minute give me a minute very good son come now oh ho what's the matter brother I am feeling full son what is the matter now look now see if If you look at the particle, you will see it is small Small particles are visible Small particles are visible Are you seeing it? Are you seeing it? Son, hurry up. Tell me, aren't you seeing these small ones? Look now. if I mix this up if I mix this up so you'll see more particles if I should I mix this up if I mix this up oh brother what's going on in the dark right now if I If I mix this then smaller particles will appear Come and feel it son, look at this now look now look at this it is visible it is visible what is this it is a type of suspension Now we can see these particles now What are we able to do with these particles If you are able to see it, then it means you are able to see it yes, how is the light getting near it son, you are passing from inside isn't it and if This is the solution. Now let me switch on the light for a minute. I turn on the light for a minute, that would be great if this solution if this solution was not like this ok if this doesn't happen then we will get light from this I can't see the light passing by we don't see it coming, okay understand Were we able to understand what we wanted to try I have tried turning off the light to see what is happening to you your collider which is your collider solution or There is a suspension, the path is visible through it, right? Right now we have the setup for the experiment If it wasn't there then you would have seen it more clearly but It's okay, right? It works in a cheap setup We will take it, if it is okay then the rest is visible I don't have it, we call it tindal Effect: Yes, you should also try it in your home tell your friends too so that they can Let's try it one last time Let's see the changes and see the difference the difference is asked again and again What are the differences between the properties So let's see quickly what are the differences Your solution comes first The particles inside are very small There are several particles here but they are big And here are the bigger ones, a lot of suspension The elder son is fine except for him Apart from this there are no solutions here there is no scattering there is no scattering There is no Tyndall effect here Scattering occurs and Tyndall effect occurs Here scattering occurs, Tyndall effect it is homogeneous this is hydrogen as this is hydrogen as okay and it's inside this The particles are not visible separately to the sugar and water If you mix it in you will not get it They are particles, they look different but These cannot be separated from milk If mixed with water, it cannot be separated Butt suspension can be easily separated If you separate the soil and water then this The table is also important son, everything is fine, I hope Till here you will get all the information clearly You must have understood everything, now we are going to study There is one last topic, after that we will do the top five We will also see questions which are physical What do you think about change and chemical change brother what is physical change what is physical change Tell me brother what is a chemical change Let me tell you, look at some physical changes There is no such change that involves any chemical There is no reaction, that means the water was in the freezer The ice kept in me changed its shape and size The state has changed, earlier it was liquid, now it is We call the whole process that became solid it is a physical change because water is water no hey brother tell me one thing friend i have h2o Even if I freeze it, it's still H2O no if it had become h5 instead of h2o then something If it was a matter then I would have accepted it, brother what is it There are chemical changes but physical changes are those changes in which the chemical properties do not change Only the physical properties are changing like state and besides that shape The size etc. is changing, we call it that what is physical change what is chemical change where bhaiya the property is getting changed assume chemical properties such as You take that paper, burn the paper Burn it now, the paper has burnt, so first the paper It was different, now the paper has been burnt, now its entire The whole property has changed, what is it This is a type of chemical change, okay brother now If you had frozen the water then put the water back converting frozen ice into water You can, I mean you can reverse it but you burnt the paper you burnt the paper burnt it and after that it turned into rock it has turned into ash now do you want to You can make paper back from that ash, can't you? If possible, that means the physical changes that take place They can be reversed Akshay Kumar It was a meme, can it be reversed like this while there is no chemical change brother I can't change this, my friend What to do, these are just some differences Read once the changes that do not result in formation of new substance any new The substance is not made but it is made here It is definitely possible during the physical changes Substance evolved does not alter there Identity of water which was the nature of water ice Even after formation, the same nature will be seen in the formation of gas even after that it will show only water Water is not double-faced like your friend Son I don't change the water but your double-faced friends are like chemical changes that Properties change their properties Physical changes can make a difference Typically B can be reversed This is a reversible reaction and it is non-reversible you won't come back you won't come back It is said that true love cannot be returned what is that also a type of non Reversible Next let's see the changes in Physical State Size Shape of the Substance R example you already know the example I gave you both, okay What is the example of melting of ice There is a very big example apart from that, chopping off vegetable biological off white what is in it An example of this is the burning of vapor have you seen rusting rusting rusting that Rust develops on iron Rust develops on iron so after that i.e. it has a brown color on it It comes in color, I will show it to you as well Give me a minute, I'll show you I will also give you the physical copy of all the things today I have arranged it for you to look at Can you see this? Now don't be scared after seeing this okay you can see this rusting on it It has started rusting, look it is brown in colour can you see it, look at this brown color I don't know if you can see it You can see it, yes, but this brown color which this is a type of rusting okay so what is resting what is rusting that is a type of chemical change because That is also a chemical property, okay So chemical change, physical change, this is our complete It's clear now let's do something quickly These chapters move towards questions Your first question ends here. Burning of candle is physical change and chemical change is very important question if I What does it feel like to make a candle physically? What do you think it might be chemical? I think I'll tell you when the candle burns If there is no combustion then it is a chemical change but but but but what about when the wax melts Neither does the wax of such a candle melt nor If melting happens, then that would be This is your physical change and this burning thing This is your chemical change i.e. when you burn if there is something then it reacts with oxygen The chemical change in your wax it's melting it's getting hot it's melting It is melting but it is not my property The wax is changing, it is still wax The candle melts even after it is lit But if it remains then it is a candle, that means it is physical there is a change as well as a chemical change okay remember This is a very good example, let's move forward Let's move on now will you tell me the watch of the following are chemical changes growth of plant When the plant is growing, there are many things inside it There are chances, son, when a plant grows Neither what plant is big nor what plant may be smaller than back then it can't be means it is irreversible and whenever it is irreversible If yes then remember this will be your chemical change So I am telling you such a trick that whenever If any question comes then you should see which thing Which thing is irreversible and can be brought back It can be converted and it will be yours Is it something that can be converted back Whatever cannot be done physically, do it chemically. Rusting of iron was told to be chemical Mixing of iron fillings in to sand iron if I mix my nails with the soil I will find out which chemical change this is and If I take it out then what is this physical thing of mine change look forward to cooking of food become Suppose your mother has cooked brinjal did you make this vegetable, did the brinjal come back If we don't go or come then this is also a type of What is a reaction? A chemical change occurs It is also considered as the digestion of food What type of chemical change is freezing Freezing of water is your physical Change water is considered as burning of candle Burning of candle is a chemical change but Melting of wax is a physical change too great friend what's up friend you are very good You have become smart, come on brother top five Big questions should be asked quickly This is an interesting and very tricky question Tell me quickly which one is ours first of the following will show tyndall effect tyndall Which of these will show effect soon? Tell me quickly, tell me who will show who The salt solution will not show Salt solution is a true solution no it will show milk yes collider too Great Son Copper Sulphate Copper Sulphate What is a solution? There is a solution that which is completely found inside the water and Whenever something is found in its entirety, it does not show starch solution which whose particles are a little thick with the help of which he does scattering it does the light and it also shows This is B and C, B and D, its answer will be correct is B and D will be its correct answer and a little bit my friend what is it you just a little bit Get active and read a little bit Get a little serious because I Let me tell you one thing and this is very I am telling you the reality, I don't know What family background do you come from? I don't know if you have ever seen your parents what did i do what are you doing but If you want to change your generation isn't it if you come from a poor home can you relate to me, a middle class person you are coming from a class family and if you If you want to change your generation then you You will have to work hard, a person can work hard isn't it so the whole generation changes and maybe You have to become that person and you have to We have to work hard, let's see which one of The Following Statements Are True for Pure Which is the best substitute for pure substances? The statement is true that pure substances contain only one kind of particle yes one kind what is it brother it is very good this is right Pure substances may be compounds and mixtures no brother the mixture is imported The friend is talking, let's see further Pure substances have the same composition through out Does their composition remain the same? tell me friend are they the same yes they are the same pure substances can be aggregated Pulfied from all elements other than nickel no no we can't do it separately Nickel is also a type of element Nickel is also a type of metal, so nickel is also If it is a pure substance then this is also wrong That means ours comes one and three one and If there is three in it then option B is your correct one This answer will come in your paper, then you You will find out that sir had got this done, don't you remember coming forward see two substances a and b was made to react to form a third compound To be brought two things and combined them chemically and created a new thing a to b so this a to b what will happen a to b what will happen a to b There will be a compound, remember what A to B hoga compound hoga which of the following is Incorrect Which of these is incorrect Tell me which are incorrect The product a to be shows the properties of substance a and B no this is incorrect brother this is incorrect This compound has to be beaten, this will tell the wrong thing You just taught me brother, you will beat me a lot now You saw the dumbbell, you saw that road I hit the house, listen to what he said I just told you brother when a compound is formed So the properties of the compound are different h2o 2 water so this is a wrong statement Looking ahead, The Product Will Always Have Fixed composition is true when compound If there is a fixed composition then this So this is correct, this is correct brother, this is correct is the product cannot be classified as Compound hey brother how can it not be classified You can do it, if it is just a compound then what is this yes it is incorrect and we have to give incorrect answer I have to find the product form is an Element Oh no brother this is also incorrect So this is also correct i.e. A CD has three options this is incorrect ok son done done let's go Now let's move on to our last question that is classified brass and diamond edge Elements and mixtures is a very nice question Look what is brass, I told you about brass I told you what alloy was and what was alloy I was remembering my son, I am not able to remember my brother I can't remember, I can't remember, there used to be alloy I told you it was a mixture, I also told you the reason, it's ok So this is the mixture and remember this Diamond is an element Diamond is an element you have to remember this thing diamond is a Element is ok son diamond is our element It would be great if you had one with this The chapter ends and Josh I hope You were high and understood things I tried a little bit practically and it was fun I came with you, I felt like this I teach you, I am teaching your senior Now I am teaching you further will teach and if you really like the lecture I felt it was beneficial and helped me understand what I was doing I just want one thing from you Which is can you Get some focus on what you want to do in life what is there to uproot, run after it and do this Run so fast that no one can stop you, okay and you will do it, have faith in yourself No, I have no faith that you will do it brother Sister you will do it, I know you have it in you My friend, you will become my passion, right? I am your brother, right? I am here today. I stand by my hard work, maybe you too will tomorrow You should be above me, I want this Friend, I want you above me Go and do something good for this country this note take care everyone and today kiss session Let's end today's lecture Now on which topic do you want the next lecture Please tell me in the comment which chapter you want take care by
