Consider a cyclic heat engine operating between two temperatures T1 and T2 (with T1 > T2). Let Q1 be the net heat transferred to the engine at T1, Q2 be the net heat transferred to the engine at T2, and W be the net mechanical work done ON the engine during one cycle. If W > 0 (work is done on the system), which of the following options represents a thermodynamically possible scenario?
