Charles's law

Description

Charles’ law is an experimental gas law which describes how gases tend to expand when heated. When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be directly related. This law describes how a gas expands as the temperature increases; conversely, a decrease in temperature will lead to a decrease in volume. For comparing the same substance under two different sets of conditions, the law can also be written as:
V1/V2=Ti/T2
The equation shows that, as absolute temperature increases, the volume of the gas also increases in proportion.
