Homework Help: Thermodynamics: Maxwell relation and thermal expansion

  1. Nov 23, 2006 #1
    Use a Maxwell relation and the third law of thermodynamics to prove that the thermal expansion coefficient beta must be zero at T=0.

    I know that B=(delta V/V)/T and I also know the Maxwell relations. I'm just not sure which one to use and how to relate it to beta.

    Do you mean

    [tex] \beta =\frac{1}{T}\left(\frac{\partial V}{\partial T}\right)_{p} [/tex]
