    A scientist says that the efficiency of his heat engine which work at source temperature \[{{127}^{o}}C\] and sink temperature \[{{27}^{o}}C\] is \[26%,\]then

    A)  It is impossible

    B)  It is possible but less probable

    C)  It is quite probable

    D)  Data are incomplete

    Correct Answer: A

    Solution :

    Carnot engine is an Ideal engine so its efficiency will be maximum \[\therefore \]    \[={{\eta }_{\max }}=\frac{400-300}{400}\times 100%=25%\] therefore 26% efficient engine is impossible
