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) at constant pressure.

Front

How do you convert Celsius to Kelvin?

Back

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

Front

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

Back

The temperature of the gas must also increase.

Front

What is the formula for Charles' Law?

Back

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

Front

What happens to the volume of a gas when it is cooled?

Back

The volume of the gas decreases when it is cooled at constant pressure.

Front

What is the initial temperature of a gas if its volume is 400 mL at 120°C and it expands to 700 mL?

Back

The initial temperature is 120°C.

Front

What is the new temperature of a gas if its volume changes from 400 mL to 700 mL at constant pressure?

Back

The new temperature is 414.75°C.

Front

If a gas has a volume of 200 mL at 27°C, what will be its volume at -33°C?

Back

The volume will be 160 mL.

Front

What is the volume of a gas at 39.0°C if it is cooled to 8.0°C?

Back

The new volume will be 1.15 L.

Front

What is the volume of a gas at 273°C if it is decreased to 100 L?

Back

The new temperature will be 273 K.
