MCQ
In the given $P$-V diagram, a monoatomic gas $\left(\gamma=\frac{5}{3}\right)$ is first compressed adiabatically from state $A$ to state $B$. Then it expands isothermally from state $B$ to state $C$. [Given: $\left(\frac{1}{3}\right)^{0.6} \simeq 0.5, \ln 2 \simeq 0.7$ ].
Which of the following statement($s$) is(are) correct?
$(A)$ The magnitude of the total work done in the process $A \rightarrow B \rightarrow C$ is $144 kJ$.
$(B)$ The magnitude of the work done in the process $B \rightarrow C$ is $84 kJ$.
$(C)$ The magnitude of the work done in the process $A \rightarrow B$ is $60 kJ$.
$(D)$ The magnitude of the work done in the process $C \rightarrow A$ is zero.
