One mole of an ideal monatomic gas undergoes a process described by the equation PV3= constant. The heat capacity of the gas during this process is
  1. 32R
  2. 52R
  3. 2R
  4. R

Solution

PV3= constant polytropic process with n = 3
C=Cv+R1-n
For monoatomic gas : Cv=3R2
C=3R2+R1-3
     =3R2-R2
     =2R2
C=R ^
