Charles' Law was named for scientist Jacques Charles, who came up with the idea for the law around 1780. The law says that when temperature increases, the volume of a gas increases, and it increases at the same rate.
Charles's law is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion.
