Charles' Law and Boyle's Law

Front

What is Charles' Law?

Back

Charles' Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) when pressure is held constant.

Front

What is Boyle's Law?

Back

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

Front

What happens to the volume of a gas when its temperature increases (at constant pressure)?

Back

The volume increases.

Front

What happens to the pressure of a gas when its volume decreases (at constant temperature)?

Back

The pressure increases.

Front

What is the relationship between pressure and volume in Boyle's Law?

Back

Inverse relationship: as one increases, the other decreases.

Front

What happens to the volume of a gas when it is cooled (at constant pressure)?

Back

The volume decreases.

Front

In Charles' Law, which two variables are compared?

Back

Volume and temperature.

Front

What is the formula for Boyle's Law?

Back

P1V1 = P2V2, where P is pressure and V is volume.

Front

What is the formula for Charles' Law?

Back

V1/T1 = V2/T2, where V is volume and T is temperature.

Front

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which a gas has zero volume, equivalent to -273.15°C or 0 K.
