Finding the equation of the adiabats.

  1. Oct 19, 2013 #1
    Working from Callen, Chapter 1:

    Find the equation of the adiabats in the P-V plane given
    [tex]
    U = AP^2V
    [/tex]

    Where A is defined as a positive constant of dimension [itex][P]^-1[/itex].

    I'm not sure what to do with this. I was thinking of solving the equation for P and then...no idea.

    If I do that I (probably incorrectly) get something like this:

    [tex]
    P = \frac{U}{V}
    [/tex]

    After plopping this into Mathematica I can see that it looks like an adiabatic curve, but there's no way the problem is that easy. So I think I'm not going about this correctly. Just looking for some pointers/guidance.

    Thanks.
