WebIf we define the Einstein temperature as 0 E = hw E /k R, then for N = N A, Equation 15.35 gives the specific heat as. Figure 15.5 shows the predicted form for the specific heat … WebEinstein quantum theory of specific heat To explain the variation of specific heat of solids with temperature Einstein assumed (1) The atoms of solids re at rest under the action of their mutual forces of attraction at absolute zero temperature i.e., the energy of solid in this state is zero. In thermodynamics and solid-state physics, the Debye model is a method developed by Peter Debye in 1912 for estimating the phonon contribution to the specific heat (Heat capacity) in a solid. It treats the vibrations of the atomic lattice (heat) as phonons in a box, in contrast to the Einstein photoelectron model, which treats the solid as many individual, non-interacting quantum harmonic oscillators. … personal wearable fitness devices air force
