    Carnot in 1824 gave an imaginary reversible cycle which demonstrates the maximum conversion of heat into work. In a cyclic process, net work done by a system is equal to

    A)  0                                

    B)  \[\Delta U\]

    C)  \[\Delta H\]                              

    D)  q

    Correct Answer: D

    Solution :

    \[\operatorname{q}=\Delta U\,-W\] If process is cyclic process Then,        \[\Delta U\,\,=\,\,0\] \[\therefore \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\operatorname{W} =q\]
