- Charles' law states that If the pressure on a particular quantity of gas is held constant, then, with any change of state, the volume will vary directly as the absolute temperature. If the temperature on a particular quantity of gas is held constant, then, with any change of state, the volume will vary directly as pressure. If the temperature on a particular quantity of gas is held constant, then, with any change of state, the volume will varies inversely as pressure.
