Hello, in this question we have a sample of nitrogen where the amount of gas, in other words, its number of moles, and its temperature are remaining constant.
00:17
The pressure and the volume are changing.
00:20
So when number of moles and temperature are constant, while the pressure and volume are changing, this is going to be a boyle's law problem.
00:30
Oils law says that pressure and volume are inversely proportional.
00:42
So that means as one goes up, the other goes down.
00:47
So right away, looking at this question, we see that the pressure is increasing.
00:52
So that means the volume must decrease.
00:54
So that means there are only two possible answers where the volume is less than the initial volume of 37 .42.
01:01
So it means the correct answer is either a or b.
01:04
So we've already narrowed it down to those two.
01:06
To determine which one it is, you're going to need the boyle's law equation...
