    A reversible engine working between the temperature limits of 600 K and 1200 K receives 50 kJ of heat. The work done by the engine will be

    A)  50 kJ                                    

    B)  100 kJ

    C)  25 kJ                                    

    D)  -25 kJ

    Correct Answer: C

    Solution :

                    Work done by the engine is given by \[\frac{W}{Q}=1-\frac{{{T}_{2}}}{{{T}_{1}}}\]      \[\frac{W}{50\times {{10}^{3}}}=1-\frac{600}{1200}\] \[W=25\times {{10}^{3}}J\]     \[=25\,kJ\,.\]
