1. The problem statement, all variables and given/known data Silver has a Fermi energy of 5.48 eV. Calculate the electron contribution to the molar heat capacity at constant volume, Cv, of Silver at 300 K. Express your result as a multiple of R. Is the value of Cv due principally to the electrons? If not, to what is it due? ans: 0.0233R 2. Relevant equations I don't know. 3. The attempt at a solution I just don't know how to approach to this problem. Should I consider Silver as a solid? Or what? If so, then would Cv be 3R ??? But how do I find a way of relate it to the energy of an electron?
