Also known as the law of volumes, Charles’s law is an experimental gas law that describes how gases tend to expand when heated. The law states that:
| When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be directly related. |

Dalton’s law of partial pressure
Dalton’s law of partial pressures states that:
| In a mixture of non-reacting gases, the total pressure exerted by the gas mixture is equal to the sum of the partial pressures of the individual gases. |
