    A Camot engine takes heat from a reservoir at \[\text{627}{{\,}^{\text{o}}}\text{C}\]and rejects heat to a sink at \[\text{27}{{\,}^{o}}\text{C}\text{.}\] Its efficiency will be

    A)  3/5             

    B)  1/3

    C)  2/3             

    D)  200/209

    Correct Answer: C

    Solution :

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