Does a solid also have two kinds of molar heat capacities C_p and C_v? If yes, is C_p > C_v? Or is C_p - C_v = R?
Ans : Yes, a solid also has two kinds of molar heat capacities, C_pand C_v. In a solid, expansion coefficient is quite small; therefore dependence of heat capacity on the process is negligible. So, C_p> C_vwith just a small difference, which is not equal to R.
