Question: The free energy F of a compressible solid (einstein's elastically coupled oscillators model) has the following form as a function of temperature T and volumen V:

F(T, V) = F_o(V) + ATln(1 - e^-E(V)/KBT)

with

F₀(V) = B/2V₀ (V - V₀)²

and E(V) given by:

E(V) = E₀ - E₁(V- V₀)/V_o

and A, B, E₀, E₁ positive constants.

1. Calculate the presion P, entropy S and internal energy U as a function of T and V. If you can, Express the result with the Bose Function

n(T, V) = (e^E(V)KBT -1)^-1

2. Estimate, at the lowest not null order on El, the diference in Cp - Cv of the heat capacities.
