Question
For a solid with a small expansion coefficient:
  1. Cp - Cv = R
  2. Cp = Cv
  3. Cp is slightly greater than Cv
  4. Cp is slightly less than Cv

Answer

  1. Cp is slightly greater than Cv

Explanation:

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, Cp is slightly greater than Cv.
