In problem number 45, we have a sample of nitrogen.
00:07
So we are assuming it's a fixed amount of nitrogen that's not changing.
00:12
And we also know that the temperature is constant.
00:15
But we see that pressure and volume are changing.
00:18
So this is going to be a boyle's law problem.
00:23
Boils law is the gas law that says that pressure and volume are inversely proportional when temperature and amount of gas remain constant.
00:33
The equation used to solve boyle's law problems is p1 times v1 equals p2 times v2.
00:44
This equation shows that inverse relationship between the pressure and volume.
00:49
When pressure goes up, volume goes down.
00:52
So for this particular problem, we're starting out with an initial pressure of 740 tor.
01:03
We have initial volume at that pressure, which is 800.
01:08
And 80 milliliters...
