Two Carnot engines are operating in series. The first one absorbs heat at a temperature of 1111 K and rejects heat to the second engine at a temperature T. The second engine receives the heat at the intermediate temperature T and rejects it to a reservoir at 300 K. Calculate T if The efficiencies of two engines are equal. A. 577 K C. 705 K B. 621 K D. 818 K The works done by the two engines are equal. A. 577 K C. 705 K B. 621 K D. 818 K
