PhysicsMediummultiple choice

A gas goes from $A$ to $B$ along path I and returns along path II on a $P$ - $V$ diagram, tracing a clockwise loop. In the complete cycle:

Answer:

A, B

Solution:

A clockwise loop gives net work by the gas. $Δ U = 0$ over a cycle, so $Q = W > 0$ : net heat is absorbed. A, B.
