Gas Law Quiz
Pd 8
Question 1
• A high altitude balloon contains 2.50 L of
helium gas at 105 kPa. What is the
volume when the balloon rises to an
altitude where the pressure is only 40.5
kPa? Assume temperature remains
constant.
Question 2
• A balloon inflated in a room at 325 ºC has
a volume of 6.80 L. The balloon is then
cooled to a temperature of 25.0 ºC. What
is the new volume if the pressure remains
constant?
Question 3
• The gas left in a used aerosol can is at a
pressure of 103 kPa at 25 ºC. If this can is
thrown onto a fire, what is the pressure of
the gas when its temperature reaches 928
ºC? Assume the volume of the can
remains constant.
Question 4
• The volume of a gas-filled balloon is 30.0L
at 40.0 ºC and 153 kPa. What is the new
volume if the balloon reaches STP?
Question 5
• Go back to the first four questions and
give the name of the specific gas law.
