Two Carnot engines A and B are operated in succession. The first one, A receives heat from a source at T = 800 K and rejects to sink at T2. The second engine B receives heat rejected by the first engine and rejects to another sink at T3 = 300 K. If the work outputs of two engines are equal, then the value of T2 is
- 100 K
- 300 K
- 550 K
- 700 K
Answer
(C) 550 K
