1. The problem statement, all variables and given/known data Calculate the isothermal compressibility and the expansion coefficient of a van der waals gas. Then show using Euler's chain relation that KR = alpha(Vm-b) 2. Relevant equations isothermal compressibility K = (-1/V) (dv/dp)t isothermal expansion alpha= (1/v)(dv/dt)p 3. The attempt at a solution I realize it has to do with partial derivatives. But beyond this i'm lost.
