WebSep 7, 2024 · Density of States. The Debye model is a method developed by Peter Debye in 1912 [ 7] for estimating the phonon contribution to the specific heat (heat capacity) in a solid [ 1]. This model correctly explains the low temperature dependence of the heat capacity, which is proportional to T3 and also recovers the Dulong-Petit law at high temperatures. WebApr 9, 2024 · One of the major applications of the law of equipartition of energy is in Meyer’s relation (empirical relation between the size of a hardness test indentation & the load needed to leave the indentation) This shows: Cp − Cv = R, Where, Cp is the molar specific heat capacity of an ideal gas at constant pressure, and
