Partial Derivative Ideal Gas

  1. Sep 17, 2012 #1
    1. The problem statement, all variables and given/known data

    Prove that
    (∂P/∂V) n,T = 1/(∂V/∂P) n,T

    n and T are supposed to mean that theyre just constants

    2. Relevant equations

    Ideal Gas

    PV=nRT

    3. The attempt at a solution

    I tried

    (∂P/∂V) n,T= ∂nRT/v/∂V = ∂nRT/V ∂V

    then im stuck here

    Why are you stuck? n, R and T are constant. Move them outside the differentiation. Now you've just got ∂(1/V)/∂V. What's that?
