    A Carnot engine working between 300 K and 600 K has a work output of 800 joules per cycle. The amount of heat energy supplied from the source to the engine in each cycle is

    A)  6400 joule        

    B)  1600 joule 

    C)  3200 joule       

    D)  800 joule

    Correct Answer: B

    Solution :

    : Efficiency \[=\frac{output}{input}=1-\frac{{{T}_{2}}}{{{T}_{1}}}\] Or \[\frac{800}{input}=1-\frac{300}{600}\Rightarrow \frac{800}{input}=\frac{1}{2}\] Or \[input=1600J\]
