Gas Laws Conceptual

Front

What happens to the temperature of a gas when the pressure is lowered?

Back

The temperature decreases.

Front

What three variables are involved in gas laws?

Back

Pressure, Temperature, Volume.

Front

What causes gas pressure?

Back

Gas pressure is caused by gas molecules colliding with the surfaces of the container.

Front

What type of relationship do pressure and volume have according to Boyle's Law?

Back

Inverse relationship.

Front

In an inverse relationship, when one variable increases, what happens to the other variable?

Back

The other variable decreases.

Front

What is Boyle's Law?

Back

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

Front

What is Charles's Law?

Back

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

Front

Define absolute zero.

Back

Absolute zero is the theoretical temperature at which a gas has zero volume and no kinetic energy, equivalent to -273.15°C.

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 the volume of a gas if the temperature increases while pressure remains constant?

Back

The volume increases.
