    What is the Derivative of P/T with respect to T?

    A free expansion I try to find the Joule coefficient (dT/dv) constant U. I must find that it's equal to -(T^2/Cv)d/dT(P/T) constant V, but I found that it's equal to (-1/Cv)(T(dP/dT)v-P)

    What is the Derivative of P/T with respect to T?

    yes! Sorry i have some problems lol! In fact it's a free expansion U=0 Q=0 and w=0

    Homework Statement Hi, i have a little problem with a demostration, I hope you can help me. Homework Equations this said that we have a system, a gas is containing in a recipe, there's no heat exchange neither work with the enviroment, only an expansion v to 2v, we have to find that...
