Question

Gases have two heat capacities, Cp and Cv. why?

Answer 1

Answer:

Cp & Cv. Gases have two specific heats because one of them refers to a change in internal energy in a system at a fixed volume. The other specific heat applies to changes in the system energy in a constant pressure scenario.
