For a gas held at constant pressure, the volume (V) occupied by the gas is directly proportional to its temperature (T). That is:
V T, orThe relationship was discovered by Jacques Charles in 1787 and is a special case of the ideal gas law. It is sometimes called Gay-Lussac's law, because Joseph Gay-Lussac established it more accurately in 1882.
