Question

For a solid with a small expansion coefficient,
(a) C_p − C_v = R
(b) C_p = C_v
(c) C_p is slightly greater than C_v
(d) C_p is slightly less than C_v

Solution

c) C_p is slightly greater than C_v

For a solid with a small expansion coefficient, work done in a process will also be small. Thus, the specific heat depends slightly on the process. Therefore, C_p is slightly greater than C_v_.
