Question

What is the unit of isothermal reversible expansion formula?

Answer 1

Explanation:

Isothermal compressibility is −1V(∂V∂P)T, so the SI units are reciprocal pressure, Pa−1 or m2 N−1. Heat capacity at constant volume is (∂E∂T)V, so its SI units are energy/temperature or J K−1. When you say specific heat capacity, that means per unit mass, so the specific heat capacity at constant volume is J kg−1K−1.
