An ideal gas undergoes 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

p V^{n} =

constant, then

n

is given by (here

C_{p}

and

C_{V}

are molar specific heat at constant pressure and constant volume, respectively.)
