For a 3D free electron gas, derive expressions for the Fermi
momentum, Fermi energy, and density of levels. Then plot the
density of levels and contrast its behavior as a function of
energy. Your answers should be expressed in terms of the electron
concentration n = N / V and some combination of fundamental
constants.

Derive the Maxwell equations for F (Helmholtz Free Energy) and G

condition of being a state function, and which of the parameters E
(Internal energy), Q (Heat), W (Work), S (Entropy) are not the
state function? Why is that?
