Question

(xi) Energy of the highest filled quantum state is .......
(a) electron energy
(b) free energy
(c) Fermi energy
(d) zero point energy​

Answer 1

Answer:

When all the particles have been put in, the Fermi energy is the kinetic energy of the highest occupied state. As a consequence, even if we have extracted all possible energy from a Fermi gas by cooling it to near absolute zero temperature, the fermions are still moving around at a high speed.
