Front

Boyle's law states that:

Back

The volume of a fixed amount of gas is inversely proportional to its pressure at constant temperature.

Front

Avogadro's law states that:

Back

Equal amounts of gases occupy the same volume at constant temperature and pressure.

Front

Charles's law states that:

Back

The volume of a fixed amount of gas is directly proportional to its temperature in Kelvin at constant pressure.
