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 :
Answer & explanation
Correct answer: option 4
PV3 = constant ; ⇒ n = 3
C = Cv + \(\frac{R}{1 - n}\)
= \(\frac{R}{r - 1}\) + \(\frac{R}{1 - n}\)
r = 5/3
⇒ C = R
