Hello, what we have here in this problem is a gas law problem where the pressure and the temperature are constant, while the moles of the gas and the volume change.
00:18
So this relationship is described by avogadro.
00:24
It's avogadro's principle.
00:31
And avogadro's principle shows that when pressure and temperature are constant, the number of moles n and the volume of a gas are directly proportional.
00:50
If the amount of gas increases, then the volume increases.
00:54
If the number of most gas decreases, then the volume would decrease.
00:59
This is very much like blowing up a balloon.
01:04
You add more air to the balloon, it gets bigger.
01:06
You let air out of the balloon, it gets smaller.
01:09
So the equation that describes this is v1 over n1 equals v2 over n2, where v is volume and is number of moles.

The numbers one represent the initial conditions, and the twos represent the new conditions...
