P-V Diagrams & Cyclic Processes

The given diagram shows four processes i.e., isochoric, isobaric, isothermal and adiabatic. The correct assignment of the processes, in the same order is given by :-

Show answer and solution

Answer: (a)

Isochoric: vertical line ( $V$ constant), so it is d.
Isobaric: horizontal line ( $P$ constant), so it is a.
Isothermal and adiabatic are both falling curves; the adiabatic is steeper (slope $-\gamma\frac{P}{V}$ versus $-\frac{P}{V}$ ), so isothermal is b and adiabatic is c.
So the answer is (a) d a b c.
