    Answer : Option C

    Explanation :

    Joule-thomson coefficient is nothing but the slope graph between temperature and pressure which is a plot obtained experimentally under constant enthalpy conditions (∂T∂P)H=μ.
    There is huge significance for this and is used to tell whether a fluid undergoes cooling or heating by throttling.
