Q. If $AB$ is an isothermal, $BC$ is an isochoric and $AC$ is an adiabatic, which of the graph correctly represents then in figure
A) [image:12_image31.jpeg]
B) [image:12_image32.jpeg]
C) [image:12_image33.jpeg]
D) [image:12_image34.jpeg]
Explanation
(b) As slope of adiabatic $AC$ is more than the slope of isothermal $AB$, and BC is isochoric ($ie$ at constant volume), therefore, figure (b) represents the curves correctly
