A gas undergoes a cyclic process a−b−c−a which is as shown in PV – InterviewSolution

1.	A gas undergoes a cyclic process a−b−c−a which is as shown in PV diagram. The process a−b is isothermal, b−c is adiabatic and c−a is a straight line on P−V diagram. Work done in process ab and bc is 5J and 4J respectively. If the area enclosed by the diagram abca in the figure is 3J, choose the correct statements.
Answer» A gas undergoes a cyclic process $a - b - c - a$ which is as shown in $P V$ diagram. The process $a - b$ is isothermal, $b - c$ is adiabatic and $c - a$ is a straight line on $P - V$ diagram. Work done in process $a b$ and $b c$ is $5 J$ and $4 J$ respectively. If the area enclosed by the diagram $a b c a$ in the figure is $3 J$ , choose the correct statements.
