Hi there.

In this question, we have a gas sample whose number of moles and temperature remain constant, while the pressure and volume change.
00:18
So this relationship is described by boyle's law.
00:22
Boyle's law says that when the number of moles and temperature are constant, the pressure of the gas and its volume are inversely proportional.
00:39
That means as one goes up, the other goes down, and vice versa.
00:47
And there is an equation to express boyle's law, and it looks like this.
00:51
It's p1 times v1 equals p2 times v2, where p is pressure, v is volume, the ones represent the initial conditions, and the twos represent the new conditions.
01:05
So based upon the information in this problem, we see that the initial pressure is 1 .71 atmospheres.
01:14
And at that pressure, we have a volume of 22 .4 liters.
01:18
What we want to know is the new pressure when the gas is compressed to 10 .6 liters...
