1.    With the help of chemical equations, explain how CFCs deplete ozone in the stratosphere.

2.    Jet airplanes often fly in the lower stratosphere, where the pressure drops to approximately 245 mm Hg. In her suitcase, a passenger packed a sealed, crumpled plastic bag with an initial volume of 0.35 L. If the baggage compartment is no pressured, what is the volume of the bag at altitude? Show your equations and work.

3.    A hot air ballon has a volume of 55,287 m3 at 60 degrees C. What is its volume at 20 degrees C? Show your work and calculations.

4.      A cylinder with a movable piston has an initial volume of 0.4 L at a pressure of 7.0 X 10^2 torr and a temperature of 40 degrees C. What will be its volume if the pressure changes to 2.0 X 10^2 torr and the temperature to 80 degrees C. Show your work and calculations

Explanation / Answer
