welcome to moomoom Math and Science in this video let's talk about three gas laws Boyle's Law Charles law and gay lussex and I think it'll be helpful if we see it all in a chart so we can see how each one is a little bit different and they're also a little the same so let's get started with Boyle's ball the constant is mass and it states that pressure and volume are inversely proportional and you can take a look at this graph and you can see that as pressure increases volume goes down and as pressure decreases the volume goes up now let's talk about density pressure and density are directly proportional so as pressure goes up so does density and the formula is P1 over V1 equals P2 over V2 p is pressure V is volume or you can see it as pressure times volume equals K which is a proportionality constant now let's move over to Charles law with this the constant is pressure and it states that temperature and volume are directly proportional and you can see in the graph that his temperature goes up so does the volume density it is inversely proportional to temperature so as temperature goes up so does the volume but the density goes down when temperature drops volume drops and density goes up the formula V1 over T1 equals V2 over T2 D is for volume T is for temperature or volume divided by temperature equals k a proportionality constant and finally we have gay lussex law which is also called the pressure in temperature law and in this case Mass is fixed and volume is a constant and it states that pressure and temperature are directly proportional so as temperature goes up so does pressure and the formula for that is P1 over T1 equals P2 over T2 where p is pressure and T is temperature so there we go three gas laws a brief introduction to all thanks for watching and remember kindness multiplies kindness be kind to someone today
