Two Carnot engines A and B are operated in succession. The first one, A receives heat form a source at T = 800 K and rejects to sink at \(T_{2} .\)The second engine B receives heat rejected by the first engine and rejects to another sink at \(T_{3}=300 K\). If the work outputs of two engines are equal, then the value of \(T_{2}\)is
- 100 K
- 300 K
- 550 K
- 700 K
Answer
(C) 550 K
