WebOct 20, 2015 · The heat capacity will be given by C = d E d T : C = ∂ T E = ( ∂ T β) ∂ β E = 1 T 2 ℏ 2 ω 2 e − β ℏ ω ( 1 − e − β ℏ ω) 2. While this term looks weird, so you could (a) plot it or (b) consider limit cases (and argue with continuity and monotonicity in between). But one can easily see that this term is continuous (so ...

Debye model - Wikipedia
WebOct 10, 2024 · The question starts from an incorrect statement. Einstein's and Debye's theories do not work well at high temperatures whatever high the temperature is.. The correct statement is that Einstein's law fails to account for the low-temperature behavior of specific heat of solids, even qualitatively, but at high temperature, it goes to the Dulong … Web1 day ago · The temperature dependence (at constant volume) of the heat capacity of a solid (in J mol − 1 K − 1) can be described by the Einstein model.
