A cycle $A BC D$ on a $P V$ diagram has $A B$ isobaric expansion, $BC$ isochoric pressure fall, $C D$ isobaric compression and $D A$ isochoric pressure rise. On a $P$ - $T$ diagram, the processes $A B$ , $BC$ , $C D$ and $D A$ are respectively:

Options:

Answer:

Solution:

Isobaric: $P$ is constant, so horizontal on a $P$ - $T$ plot ( $T$ rises in expansion and falls in compression). Isochoric: $P \propto T$ , so a straight line through the origin. $BC$ is a pressure fall (moves toward the origin) and $D A$ a rise. A.
