2. To what pressure must a gas be compressed
in order to get into a 3.00 cubic foot tank the entire weight of a gas
that occupies 400.0 cu. ft. at standard pressure?
3. A gas occupies 1.56 L at 1.00 atm. What
will be the volume of this gas if the pressure becomes 3.00 atm?
4. A gas occupies 11.2 liters at 0.860
atm. What is the pressure if the volume becomes 15.0 L?
5. 500.0 mL of a gas is collected at 745.0
mm Hg. What will the volume be at standard pressure?
6. Convert 350.0 mL at 740.0 mm of Hg to
its new volume at standard pressure.
7. Convert 338 L at 63.0 atm to its new
volume at standard pressure.
8. If the pressure on a gas is decreased
by one-half, how large will the volume change be?
9. A gas occupies 4.31 liters at a pressure
of 0.755 atm. Determine the volume if the pressure is increased to 1.25
10. 600.0 mL of a gas is at a pressure
of 8.00 atm. What is the volume of the gas at 2.00 atm?
11. You are now wearing scuba gear and
swimming under water at a depth of 66.0 ft. You are breathing air at 3.00
atm and your lung volume is 10.0 L. Your scuba gauge indicates that your
air supply is low so, to conserve air, you make a terrible and fatal mistake:
you hold your breath while you surface. What happens to your lungs? Why?
12. How many cubic feet of air at standard
conditions (1.00 atm.) are required to inflate a bicycle tire of 0.50 cu.
ft. to a pressure of 3.00 atmospheres?
