    For a Car not engine, the source is at 500 K and the sink is at 300 K. What is the efficiency of this engine?

    A)  1.2                 

    B)       0.4                 

    C)       0.9                 

    D)       0.3                             

    Correct Answer: B

    Solution :

    Here,\[{{T}_{1}}=500\,K,\,{{T}_{2}}=300\,K\] On using \[\eta =\frac{{{T}_{1}}-{{T}_{2}}}{{{T}_{1}}}\] \[=\frac{(500-300)}{500}\] \[=\frac{200}{500}\] \[=0.4\] Hence, the correct option is (b).
