# joule Thomson effect is isoenthalpic so delta H = 0 #Adiabatic free expansion of a gas Because there is no external pressure for the gas to expand against, the work done by or on the system is zero. Since this process does not involve any heat transfer or work, the first law of thermodynamics then implies that the net internal energy change of the system is zero. delta H =0
