    A system is changed from state A to state B by one path and from B to A another path. If \[{{E}_{1}}\] and \[{{E}_{2}}\] are the corresponding changes in internal energy, then [Pb. PMT 2001]

    A)                 \[{{E}_{1}}+{{E}_{2}}=-ve\]         

    B)                 \[{{E}_{1}}+{{E}_{2}}=+ve\]

    C)                 \[{{E}_{1}}+{{E}_{2}}=0\]             

    D)                 None of these

    Correct Answer: D

    Solution :

              \[\Delta E=0\]for a cyclic process.
