2. A scuba diver taking photos of a coral reef 60 ft below the ocean surface breathes out a stream of bubbles. What is the total gas pressure of the bubbles at the moment they are released? What is the pressure when the bubbles get to the surface?

3. Name 3 ways the volume occupied by a sample of gas can be decreased.

4. IDEAL GAS LAW

5. A 1.00 g sample of water is allowed to vaporize completely inside a 10.0-L container. What is the pressure of the water vapor at a temperature of 150˚C?

6. Gas Density

7. Calculate the density of dry air at 25˚C and 1.00 atm if its molar mass (average) is 28.96 g/mol.

8. Prove that putting Helium in a balloon will make it rise.

9. How Can Chlorofluorocarbons (CFCs) Get to the Stratosphere If They're Heavier than Air?
