Two Carnot engines A and B are operated in succession. The first one, A receives heat from a source at T₁=800 K and rejects to sink at T2 K. 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 - VgyanHub
