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):

Options

A. `n = (C- C _(p))/(C - C_(v))`
B. `n = (C_(p)-C)/(C - C _(v))`
C. `n= (C -C_(v))/(C - C _(p))`
D. `n = (C_(p))/(C _(v))`

Answer

A
