The amount of heat required to increase the temperature of a unit mass of a solid by a unit amount. The term "specific heat" is short for "specific heat capacity" of a solid. It is determined by the vibrations of the solid s atoms or excitations of its electrons and also by a variety of phase transitions.

A useful step on the way to understanding the specific heats of solids was Einstein s proposal in 1907 that a solid could be considered to be a large number of identical oscillators. The quantum approach to the harmonic oscillator gives a series of equally spaced quantized states for each oscillator the separation being hf where h is Planck s constant and f is the frequency of the oscillator.
