MCQ
For a solid with a small expansion coefficient:
- A$C_p-C_v=R $
- B$ C_p=C_v$
- ✓$C_p$ is slightly greater than $C_v$
- D$C_p$ is slightly less than $C_v$
✓
Answer
Correct option: 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 $C_v$.
Thus, the specific heat depends slightly on the process.
Therefore, $C_p$ is slightly greater than $C_v$.
