WebSodium has a volume expansion coefficient of 15 ∗ 10 − 5 K − 1. Calculate the percentage change in the fermi energy as the temperature is raised from T = 0 K to T = 300 K. My … The Fermi energy is only defined at absolute zero, while the Fermi level is defined for any temperature. The Fermi energy is an energy difference (usually corresponding to a kinetic energy ), whereas the Fermi level is a total energy level including kinetic energy and potential energy.
