    Which of the following statements is correct for any thermodynamic system?

    A) The internal energy changes in all             processes

    B)  Internal energy and entropy are state functions

    C)  The change in entropy can never be zero

    D)  The work done in an adiabatic process is always zero

    Correct Answer: B

    Solution :

                    Internal energy does not change in isothermal process. \[\Delta S\] can be zero for adiabatic process. Work done in adiabatic process may be non-zero.
