The density of copper is 8.96 gm/cm3, and its atomic weight is 63.5 gm/mole.
(a) Calculate the Fermi energy for copper (Equation 5.43). Assume q = 1, and give your answer in electron volts.
(b) What is the corresponding electron velocity? Hint: Set . Is it safe to assume the electrons in copper are nonrelativistic?
(c) At what temperature would the characteristic thermal energy
(d) Calculate the degeneracy pressure (Equation 5.46) of copper, in the electron gas model.
