Charles' 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 the formula for Charles' Law?

Back

The formula is V1/T1 = V2/T2, where V is volume and T is temperature in Kelvin.

Front

How do you convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature.

Front

If the temperature of a gas increases, what happens to its volume at constant pressure?

Back

The volume increases.

Front

If the temperature of a gas decreases, what happens to its volume at constant pressure?

Back

The volume decreases.

Front

What happens to the volume of a gas if the temperature is doubled, assuming constant pressure?

Back

The volume also doubles.

Front

A gas has a volume of 2 L at 300 K. What will be its volume at 600 K?

Back

The volume will be 4 L.

Front

What is the initial volume of a gas if it has a final volume of 8 L at 400 K and is cooled to 200 K?

Back

The initial volume is 4 L.

Front

What is the relationship between temperature and volume in Charles' Law?

Back

They have a direct relationship; as one increases, the other increases.

Front

What is the significance of holding pressure constant in Charles' Law?

Back

Holding pressure constant allows for a clear observation of the relationship between volume and temperature.
