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
Answer: (B) d a b c
All four processes start from the same state.
- Isochoric (constant $V$): vertical line, $d$.
- Isobaric (constant $P$): horizontal line, $a$.
- Isothermal and adiabatic expansions both lower $P$, but the adiabatic curve is steeper ($PV^\gamma$ constant with $\gamma > 1$). So isothermal is $b$ and adiabatic is $c$.
Order: d a b c.
