Need help understanding this thermo. derivation

  1. Apr 6, 2013 #1
    Im trying to understand this concept of deriving an expression for ([itex]\frac{\partial T}{\partial P}[/itex])s in terms of T, V, Cp, [itex]\alpha[/itex], and [itex]\kappa[/itex]T

    ([itex]\frac{\partial T}{\partial P}[/itex])s is evaluated by measuring the temperature change and the specific volume change accompanying a small pressure change in a reversible adiabatic process.

    I attached the derivation that the book does, but I cannot follow it. Any help would be greatly appreciated!

    There are a lot of steps in that simple looking derivation. Where are you lost?

    Don't understand the notation in your thumbnail, but append my derivation, expressed in ordinary partial derivative notation.

    Thanks dude, I was getting lost with the notation as well. This helps out big time.. Not sure what the book was doing lol.
