WebHistory. The effect is named after James Prescott Joule and William Thomson, 1st Baron Kelvin, who discovered it in 1852.It followed upon earlier work by Joule on Joule expansion, in which a gas undergoes free expansion in a vacuum and the temperature is unchanged, if the gas is ideal.. Description. The adiabatic (no heat exchanged) expansion of a gas may … WebJoule studied the nature of heat, and discovered its relationship to mechanical work. This led to the law of conservation of energy, which in turn led to the development of the first …
