1. A 10 L balloon contains helium gas at a pressure of 655 torr. What is the new pressure when
the volume expands to 32 L at a constant temperature?
2. A sample of carbon dioxide gas occupies 8.20 L at 135° Celsius. Calculate the temperature at
which the gas will occupy 3.64 L if the pressure remains constant.
3. A gas has a pressure of 1200 torr at 155° Celsius. What is the final pressure of the gas after
temperature has dropped to 0° Celsius?
4. Calculate the pressure exerted by 3 moles of oxygen gas, O2, confined to a volume of 510 mL
at 10° Celsius.
