JEE MainPhysicsHeat and ThermodynamicsMCQ+4 / −1
An ideal gas undergoes a quasi static, reversible process in which its molar heat capacity CCC remains constant. If during this process the relation of pressure PPP and volume VVV is given by PVn=P{V^n} =PVn= constant, then nnn is given by (Here Cp{C_p}Cp​ and Cv{C_v}Cv​ are molar specific heat at constant pressure and constant volume, respectively:
  1. A
    n=Cp−CC−Cvn = {{{C_p} - C} \over {C - {C_v}}}n=C−Cv​Cp​−C​
  2. B
    n=C−CvC−Cpn = {{C - {C_v}} \over {C - {C_p}}}n=C−Cp​C−Cv​​
  3. C
    n=CpCvn = {{{C_p}} \over {{C_v}}}n=Cv​Cp​​
  4. D
    n=C−CpC−Cvn = {{C - {C_p}} \over {C - {C_v}}}n=C−Cv​C−Cp​​
