Gas Law Test Review

Front

What describes the motion of a gas molecule?

Back

Molecules are spread far apart, move in constant random motion, and travel in a straight path.

Front

If pressure goes down in a container, what happens to volume when the temperature is held constant?

Back

Volume increases.

Front

When pressure increases, what happens to the volume?

Back

Volume decreases.

Front

If temperature goes down in a container, what happens to volume when the pressure is held constant?

Back

Volume decreases.

Front

Which of the following is NOT a unit of Pressure: mmHg, atm, kelvin, psi?

Back

Kelvin is NOT a unit of pressure.

Front

Define Boyle's Law.

Back

Boyle's Law states that at constant temperature, the pressure of a gas is inversely proportional to its volume.

Front

What is Charles's Law?

Back

Charles's Law states that at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.

Front

What is the ideal gas law equation?

Back

PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.

Front

What happens to gas pressure if the volume decreases while temperature remains constant?

Back

Gas pressure increases.

Front

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

Back

At constant volume, the pressure of a gas is directly proportional to its temperature in Kelvin.
