Question

2000 L of gas is used to fill the balloons = 1/0.5 x 2000 = 4000 balloons
PRACTICE PROBLEMS
Problem 7.1. The long cylinder of a bicycle pump has a volume of 1131 cm and is filled with
air at a pressure of 1.02 atm. The outler valve is sealed shut and the pump handle is pushed down
until the volume of the air is 517 cm. Compute the pressure inside the pump.
[Ans. 2.23 atm]
Problem 7.2. Some nitrogen is held in 92.00 L tank at a pressure of 3.00 atm. The tank is
connected to a 5.00L tank that is completely empty (evacuated), and valve is opened to connect the
two. Determine the total pressure in the two-tank system after the nitrogen stops flowing. Assume
that no temperature change occurs during the process.
[Ans. 2.85 atm
Problem 7.3. The volume of a sample of acetylene, C2H2 is 1.86L at 831 torr and 27°C. What
volume will it occupy at 27°C and 477 torr?
[Ans. 3.24L]
Problem 7.4. Sulphur dioxide (SO2), a gas responsible for the formation of acid rain, is found
in the erhaust of automobiles and power plants. Consider a 1.53 L sample of gaseous SO, at a
pressure of 5.6 x 10 Pa. If the pressure is changed to 1.5 X 10^ Pa at a constant temperature, what
will be the new rolume of the gas?
[Ans. 0.57L]
Problem 7.5. Calculate the final volume when the pressure on 1.0LH changes from 2.20 k Pa
to 3.00 atm.
[Ans. 7.2 x 10-3L]
Problem 7.6. The volume of a certain gas was found to be 1600 cm when the pressure was 800
mm. If the volume is decreased to 80% of the original volume, what is the change in pressure?
[Ans. 200 mm
