    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 environment, only an expansion v to 2v, we have to find that...
