Does a Solid Also Have Two Kinds of Molar Heat Capacities Cp and Cv? If Yes, is Cp > Cv? Or is Cp − Cv = R? - Physics

Answer in Brief

Does a solid also have two kinds of molar heat capacities Cp and Cv? If yes, is Cp > Cv? Or is Cp − Cv = R?

Solution

Yes, a solid also has two kinds of molar heat capacities, Cp and Cv. In a solid, expansion coefficient is quite small; therefore dependence of heat capacity on the process is negligible. So, Cp > Cv with just a small difference, which is not equal to R.

  Is there an error in this question or solution?
