Charles's law [chärl′ziz]
n.
〚after J. Charles (1746-1823), Fr physicist〛
the statement that for a body of ideal gas at constant pressure the volume is directly proportional to the absolute temperature

* * *

      a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant. This empirical relation was first suggested by the French physicist J.-A.-C. Charles (Charles, Jacques-Alexandre-César) about 1787 and was later placed on a sound empirical footing by the chemist Joseph-Louis Gay-Lussac (Gay-Lussac, Joseph-Louis). It is a special case of the general gas law and can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas. Measurements show that at constant pressure the thermal expansion of real gases, at sufficiently low pressure and high temperature, conforms closely to Charles's law. See also perfect gas.
