Concepts for specific heat
... In order to be thermally excited the electrons have to occupy levels above this Fermi energy. As EF is huge compared to the thermal energy of kB T = 25 meV, we find that the vast majority of electron is frozen in and does not contribute to the specific heat. Thus cv is much smaller than the value N ...

Conservation of energy
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can be neither created nor be destroyed, but it transforms from one form to another, for instance chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist. That is to say, no system without an external energy supply can deliver an unlimited amount of energy to its surroundings.
