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. WebQ. Pressure-temperature relationship for an ideal gas undergoing adiabatic change is: γ=Cp/Cv Q. During an adiabatic process, if the pressure of the ideal gas is proportional to the cube of its temperature, the ratio γ= Cp Cv is ( Cp = Specific heat at constant pressure ; Cv= Specific heat at constant volume) Q.
