Question

For a solid, what is the total energy of an oscillator?

Answer 1

A solid was thought of as being composed of an assemble of non interacting ion cores that behaved as simple harmonic oscillator,vibration about an equilibrium position ,in thermal equilibrium at a given temperature

Answer 2

Answer:

The internal energy of a solid is associated with kinetic energy and potential energy of vibrating atoms about their equilibrium positions. Solid is having 6 degrees of freedom.

Total energy of an oscillator=6×1/2KTN

=3KT×N

=3RT. (KN=R)

Here K is Boltzmann constant

N is avogadro number
