An ideal gas under goes a quasi static, reversible process in which its molar heat capacity C remains constant. If during this process the relation of pressure P and volume V is given by `PV^n=constant`, then n is given by (Here `C_P and C_V` are molar specific heat at constant pressure and constant volume, respectively):A. `n=(C_(P))/(C_(V))`B. `n=(C-C_(P))/(C-C_(V))`C. `n=(C_(P)-C)/(C-C_(V))`D. `n=(C-C_(V))/(C-C_(P))` |
