Joule Thomson Effect

  1. Feb 13, 2010 #1
    It occurs when a real gas is allowed to expand adiabatically


    we all know when a ideal gas is expanded adiabatically it temperature decreases
    so real gas should do the same with minor difference




    so what is all the fuss about we all know it will happen

    why is it given a special name

    Question: did you look at wikipedia before posting?

    You seem to be thinking of isentropic, not general, adiabatic expansion.

    This can increase temperature.

    So unique thing about joule thomson effect is increasing of temperature on expansion

    In addition to the above comments, historically, measurement of the Joule-Thompson coefficient led to the development of the absolute (Kelvin) temperature scale.
