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

Question

In an isochoric process, volume remains constant while in isobaric process, pressure remains the same.Slope of an isothermal process is given as

−

P

V

- \frac{P}{V}

while for an adiabatic process, slope of

P

−

V

P - V

curve is

−

γ

P

V

- \frac{\gamma P}{V}

, where

γ

>

1

\gamma > 1

.

∴

herefore\

Adiabatic curve is steeper than isothermal curve.
