When a system is taken from state i to state f along path iaf in figure, Q=50cal and W=20cal. Along path ibf,Q=36cal. If W=−13cal for the return path fi, what is Q for this path?

Solution
Since the curved path is traversed from f to i the change in internal energy is −30cal and Q=ΔEiny+W=−30cal−13cal=−43cal
