    A Carnot engine takes heat from a reservoir at 627°C and rejects heat to a sink at 27°C. Its efficiency will be

    A) 3/5                                        

    B) 1/3

    C) 2/3                                        

    D) 200/209

    Correct Answer: C

    Solution :

    \[\eta =1-\frac{{{T}_{2}}}{{{T}_{1}}}\] \[\therefore \]      \[\eta =1-\frac{(27+273)}{(273+627)}\] \[=1-\frac{300}{900}=\frac{600}{900}=\frac{2}{3}\]
