Correct Answer: Cp - Cv = R/J
Solution : The Correct Answer is - Cp - Cv = R/J
Gases have two different specific heats: specific heat at constant volume (Cv) and specific heat at constant pressure (Cp). A change in internal energy in a system at a fixed volume is the subject of one of the specific heats that apply to gases. In a scenario with constant pressure, the other specific heat is applicable to changes in the system's energy. Cp is always greater than Cv as a result. Cp - Cv = R/J shows how they are connected. This connection is known as Mayer's Relation.
