If the volume of a gas is doubled at constant temperature, the factor by which the pressure increases is:
A barometer filled with an unknown liquid has a height of 1 m at 1 atm. During stormy weather, the height
of the column is observed to rise to 1.3 m. What is the atmospheric pressure?
Which of the following are possible units of R?
What are the conditions of STP?

All of the following are properties of an ideal gas except:
The ideal gas law is most valid under these conditions:
For the van der Waals equation:
For the equation
PV = nRT
, the value of T must be expressed in:

Unfortunately, James' feet are not so big. Barefoot, his weight is spread over
. What is the ratio of
the pressure he exerts on the ground barefoot over the pressure he exerts with his shoes on?
The "air" in airbags is generated via the decomposition of solid
A sample of an ideal gas is compressed at constant temperature. What happens to the average
kinetic energy of the molecules?
A piston compresses a gas at constant temperature. Initially the gas occupied 1 L and was at a pressure of 1
atm. After compression, the gas occupies 0.1 atm. What is the pressure of the compressed gas?
A collaborator from a foreign country reports that the value of
