One mole of an ideal monatomic gas undergoes a process described by the equation P V 3 = constant. The heat capacity of the gas during this process is

Step-by-step solution

P V 3 = constant polytropic process with n = 3 C = C v + R 1 - n For monoatomic gas : C v = 3 R 2 C = 3 R 2 + R 1 - 3 = 3 R 2 - R 2 = 2 R 2 C = R
