The number of specific heats that a gas can have is? Which of the following three options is correct? 1. Only one. 2. Only two. 3. Infinite

We know that a gas has two specific heats - Cp(Specific heat at constant pressure) and Cv(Specific heat at constant volume). I answered option 2 but the correct option according to the question paper solution is option 3. So, why does a gas have infinite number of specific heats and how do I conceptualise this? Is each specific heat realted to a unique thermodynamic process?
