Q.
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 :
isochoric → Process d
isobaric → Process a
Adiabatic slope will be more than isothermal
so
Isothermal → Process b
Adiabatic → Process c
order → a d a b c
