    When heat is given to a gas in an isothermal change, the result will be    [MP PET 1995; RPMT 1997]

    A)            External work done          

    B)            Rise in temperature

    C)            Increase in internal energy

    D)            External work done and also rise in temp.

    Correct Answer: A

    Solution :

                       In isothermal change, temperature remains constant, Hence DU = 0.            Also from  \[\Delta Q=\Delta U+\Delta W\] Þ \[\Delta Q=\Delta W\]
