MCQ
A cyclic process $ABCA$ is shown in $PT$ diagram. When presented on $PV$, it would
  • A

  • B


  • D

Answer

Correct option: C.

c
In the given cyclic process, From $A$ to $B$, the pressure is constant.

From $C$ to $A, P \propto T$

Hence, the volume is constant.

From $B$ to $C$, the temperature is constant.

Hence, $P \propto \frac{1}{V}$

From $C$ to $A,$ volume is constant.

Hence, when presented on $P V,$ it would be represented by option $\mathrm{C}$.
