[Music] Hey you guys, this is Mr. Millings and today we're going to learn about intensive versus extensive properties of matter. So let's take a look here at what intensive properties are. It says that intensive properties are properties of a substance that do not depend on the amount of matter present. So what does that mean? Well, let's suppose we have a beaker here. And this beaker is filled with a lot of water. And we have a beaker here. And this beaker right here is not filled with very much water at all. And I were to ask you, hey, what is the boiling point of this water? Uh, if I ask you what the boiling point of beaker 1's water is, you might say it's 100° C, right? And if I ask you what the boiling point of beaker 2's water is, you might also say that it's 100° C. That is because things like boiling point are intensive properties of matter. It doesn't matter how much substance you have, the boiling point of water is going to be the same. Whether you have a lot or just a little bit, the boiling point of water is going to be 100° C. Right? So things like boiling point, freezing point, melting point, and condensation point, all these are examples of intensive properties, properties of a substance that do not depend on the amount of matter present. If I were to ask you, hey, what is the density of this water right here in beaker 1? You might tell me that the density of the water in beaker 1 is 1 gram per mill 1 g per milliliter. And if I were to ask you what the density of the water in beaker 2 is, you might also tell me that it's also 1 g per milliliter. So it really doesn't matter how much water you have. The density of water is going to be one gram per milliliter whether you have a lot of it or just a little bit. That is because density is an intensive property of matter. A property that doesn't depend on the amount of of uh of matter present. What about hardness? In earth science, you learned about the hardness scale in regard to different minerals. And you learned that diamond is the hardest uh mineral there is, right? And so it doesn't matter how much diamond you have, whether you have a big diamond or a little diamond, they both have the same hardness to them. Things like color also is an intensive property. things like flammability or combustibility or corrosiveness. These are also intensive properties. For example, if you have a lot of gasoline, it's going to be equally as flammable as if you have just a little quantity of gasoline. For example, oxygen is combustible regardless of whether you have a lot or a little bit. It's going to be combustible. And last but not least, battery acid is going to be corrosive. Regardless of whether you have a lot of battery acid or a little bit of battery acid, that too is going to be corrosive. Okay, so intensive properties once again are properties of a substance that do not depend on the amount of matter present. Let's now take a look at extensive properties and see how they work. Okay, so extensive properties of matter are properties of a substance that do depend on the amount of matter present. For example, if I were to ask you, hey, what is the volume of water? You might say to me, well, it depends on how much water you have. That is because volume is an extensive property of matter. If I were to ask, hey, what is the mass of copper? You might say, well, it really depends on how much copper you have. That is because mass is an extensive property of matter. If I said, hey, what is the length of uh of copper or a copper bar? You might say, well, it depends on how big the copper bar is, and it depends on how much you have. And last but not least, if I were to say, hey, what is the weight of of this copper here? You might say, or of copper in general, you might say it depends on how much copper you have. So things like volume, mass, length, and weight are going to be extensive properties of matter. Properties of a substance that depend on the amount of matter present. So let's take a look at a few examples and determine whether or not they are intensive or extensive properties of matter. Okay, just to summarize here, we're just going to work through a few example prop properties of matter and determine whether or not they're extensive or intensive. So volume, if we take a look, volume, if I said, hey, what is the volume of water? Like we just said, it's going to depend on how much you have. So that's going to be an extensive property of matter. Volume is extensive. So is mass. It's going to depend on how much you have. So that too will be an extensive property of matter. What about density? The density of water is always 1 gram per milliliter no matter how much you have. So that is going to be an intensive property. What about flammability? Once again, uh gasoline is is flammable regardless of how much you have. So that's going to be intensive. Uh corrosive, same thing. Doesn't matter how much you have, that's going to be an intensive property as well. Whoops, I misspelled that. No big deal. We'll just cross that out. An intensive property as well. What about boiling point? Well, boiling point, water boils at 100° Celsius at sea level regardless of how much you have. So, that too is going to be intensive. Uh combustibility. If we take a look at combustibility, oxygen is combustible regardless of how much you have. Doesn't matter how much you have. So, it's going to be intensive. freezing point same thing and melting point doesn't matter how much you have uh they're going to freeze and boil at the same temperature so that is going to be intensive as well okay so most of these are going to be intensive properties of matter doesn't matter how much you have okay so that uh that's an explanation of intensive and extensive properties and uh if you like what you see go ahead and click that little bomb in the bottom right hand corner and that will subscribe you to my channel and feel free to leave any comments in the comment section down below and uh I hope this was helpful.
