    The heat change at constant volume \[({{q}_{v}})\] is equal to

    A)  \[\Delta E\]                                       

    B)  \[\Delta H\]

    C)  RT                                         

    D)  \[\Delta G\]

    Correct Answer: A

    Solution :

                    From first law of thermodynamics, \[\Delta E=q+W\] or            \[\Delta E=q+p\Delta V\] At constant volume, \[\Delta V=0\] \[\therefore \]  \[p\Delta V=0\] or            \[\Delta E={{q}_{v}}\]
