Question

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

Answer 1

Answer:

$C_p$ is greater then $C_v$ ($C_p>C_v)$

Explanation:

• Yes, a solid has two types of molar heat capacities too, Cp and Cv.
• In a solid, coefficient of expansion is quite small therefore it is negligible to depend on the heat capacity of the device.
• So, $C_p>C_V$  with only a slight difference, which is not equal to R.

Heat capacity:-  

1. The ratio of heat that a material absorbs to the change in temperature.
2. The calorie heat capacity per gram is called heat specific.
3. The calorie measure is dependent on the specific water heat.
