1 ME 501 Example Problem: Electron Gas in Metals The temperature of a 1.0 cm 3 copper metal crystal is raised from T 1 = 400 K to T 2 = 500 K. Calculate the internal energy change of the crystal   21 UU due to lattice vibrations  vib and due to the free electron gas   elec . Assume that the temperature is high enough that the Einstein model is accurate for determining the internal energy due to lattice
