A PV diagram is shown in the figure with three isotherms at temperature T1, T2 and T3. Four processes are represented in the diagram and are identified as 1, 2, 3 & 4. Then the processes indicated in the diagram are

A. 1 – Isothermal, 2 – Isobaric, 3 – Isochoric & 4 - Adiabatic
B. 1 – Isochoric, 2 – Isothermal, 3 – Adiabatic & 4 - Isobaric
C. 1 – Isobaric, 2 – Isothermal, 3 – Adiabatic & 4 - Isochoric
D. 1 – Isobaric, 2 – Adiabatic, 3 – Isothermal & 4 - Isochoric
Answer» D. 1 – Isobaric, 2 – Adiabatic, 3 – Isothermal & 4 - Isochoric
