Thermodynamic Properties of a Gas

[chhitiz]

this might seem trivial but i have no thermo books on hand and i can't remember what we call those properties whose value depends only on initial and final states of gas but not on the process adopted to reach final state?

 

[chhitiz]

don't bother. found it could anybody tell me instead the equation of how C_v varies if both P and V are changing?

By definition Cv only exists when V is a constant.
