Question

Two Carnot engines A and B are operated in series. The first one, A, receives heat at T₁(= 600 K) and rejects to a reservoir at temperature T₂. The second engine B receives heat rejected by the first engine and, in turns, rejects to a heat reservoir at T₃ (=400 K). Calculate the temperature T₂ if the work outputs of the two engines are equal:
(A) 600 K (B) 400 K
(C) 300 K (D) 500 K
