Two thermodynamical process are shown in the figure. The molar heat capacity for process $A$ and $B$ are $C_{A}$ and $C_{B}$ . The molar heat capacity at constant pressure and constant volume are represented by $C_{P}$ and $C_{V}$ , respectively. Choose the correct statement.

For process A : log P = γ log V ⇒ P = V γ , ( γ > 1 ) P V - γ = Constant C A = C V + R 1 + γ … i Likewise, for process B → P V - 1 = Constant C B = C v + R 1 + 1 C B = C v + R 2 … ii Also, C P = C v + R … iii By ii and iii , we get C P > C B > C v
