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 :-

Figure

Show answer and solution

Answer: (a)

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