Boyle’s Law #1
The pressure and the volume of a gas
are indirectly proportional when
the temperature and number of moles
remain constant.
P1V1 = P2V2

3. Imagine that you had a container which could easily change volume. Suppose that in the container
you had a volume of 6.4 liters of oxygen gas at 1.0 atmospheres of pressure. If you wanted to
increase that pressure to 3.2 atmospheres, what volume would your container have to be?
4. Now imagine that a helium balloon in the shape of Winnie the Pooh ™ is placed in a pressure
chamber. If Winnie has a volume of 22.4 liters and 1.00 atmospheres before the chamber is
activated, what the pressure pushing on Winnie when his volume is 3.45 liters?

5. A mercury barometer works because the air pressure outside pushes on the mercury inside causing
the volume of air trapped above the mercury to change. If the volume of air above the mercury is
100. mL at 760 mmHg, what will the volume be at 781 mmHg?
___________
6. A sample of oxygen gas occupies a volume of 0.250 L at 740. torr pressure. What volume will it
occupy at 800 torr pressure?
