In the given P-V diagram, a monoatomic gas $$\left(\gamma = \dfrac{5}{3}\right)$$ is first compressed adiabatically from state A to state B. Then it expands isothermally from state B to state C. [Given: $$\left(\dfrac{1}{3}\right)^{0.6} = 0.5$$, 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 $$\to$$ B $$\to$$ C is 144 kJ.

B

The magnitude of the work done in the process B $$\to$$ C is 84 kJ.

C

The magnitude of the work done in the process A $$\to$$ B is 60 kJ.

D

The magnitude of the work done in the process C $$\to$$ A is zero.
