Joule-Thomson effect

n
a change in temperature of a thermally insulated gas when it is forced through a small hole or a porous material. For each gas there is a temperature of inversion above which the change is positive and below which it is negative. Also called: Joule-Kelvin effect
[C20: named after James Prescott Joule and Sir William Thomson, 1st Baron Kelvin]
