Unit 10: Gas Laws Review

Front

What happens to matter as its temperature increases?

Back

The particles gain kinetic energy.

Front

Which equation do you need to use when a gas's pressure changes?

Back

P1/T1 = P2/T2.

Front

Rank the following gases in order of increasing rate of effusion: Xe, Ne, Ar, He, N2.

Back

Xe < Ar < N2 < Ne < He.

Front

How do you convert pressure from torr to psi?

Back

783 torr is approximately 15.1 psi.

Front

What happens to volume when temperature increases?

Back

Increase.

Front

Define kinetic energy in the context of gas particles.

Back

Kinetic energy is the energy of motion; as temperature increases, gas particles move faster.

Front

What is the relationship between pressure and volume in a gas at constant temperature?

Back

Boyle's Law: P1V1 = P2V2.

Front

What is the ideal gas law equation?

Back

PV = nRT.

Front

What does R represent in the ideal gas law?

Back

R is the ideal gas constant.

Front

Explain Graham's Law of Effusion.

Back

The rate of effusion of a gas is inversely proportional to the square root of its molar mass.
