Hi there.
00:03
In this problem, we have a sample of nitrogen gas, and we are told that it's in a, we're assuming a closed container, otherwise it would escape, and that the volume of this container is constant.
00:19
So that means that the number of moles of gas, or the amount of gas, and the volume are constant, while pressure and temperature vary.
00:39
Well, when nnv are constant and pressure and temperature vary, what we have is gaylu -sax law.
00:54
And gayleu -sack's law says that pressure and temperature are directly proportional.
01:00
As one goes up, the other goes up.
01:02
And as one goes down, the other goes down.
01:05
So that gives us the equation, p1 over t1 is going to be equal to p2 over t2.
01:14
Remembering that our temperatures must be in kelvin.
01:18
In any gas law, we have to work with absolute temperature.
01:22
So the temperature has to be in kelvin.
01:24
Well, we have a plan here.
01:26
We have an equation.
01:27
So let's pull the information that we have out of this problem.
01:31
Let's see.
01:32
We have an initial pressure of 1 .35 atmospheres...
