Q. One mole of an ideal monatomic gas undergoes a process described by the equation $PV^3$ = constant. The heat capacity of the gas during this process is
A) $\frac{3}{2}R$
B) $\frac{5}{2}R$
C) 2R
D) R
Explanation
[Solution] For a polytropic process $C = C_V + \frac{R}{1 - n} = \frac{3}{2}R - \frac{R}{2} = R$. Answer (4).
