Hi everyone!
1. Homework Statement
Given is a function for the internal energy: ##U(T,V)=Vu(T)##
Asked is to derive the entropy balance equation. In order to do so i need to find the "isothermal and adiabatic compressibility": $$\kappa_{T}=-\frac{1}{V}\left(\frac{\partial V}{\partial P}\right)_{T}$$
[/B]
In order to calculate ##\kappa_{T}## I need to find a function ##V(P,T)## right? But how do I get this function from the given internal energy function?
Thanks for your help!
