    In an isothermal expansion of an ideal gas:

    A) \[W=0\]                              

    B) \[\Delta E=0\]

    C) \[q=0\]                

    D)  \[\Delta V=0\]

    Correct Answer: B

    Solution :

    Key Idea: Find basic definition of thermodynamics. [a] In isothermal process, temperature and internal energy remains constant.\[(\Delta E=0)\] [b] \[\Delta q=0-\]Adiabatic process [c] \[\Delta V=0-\]Isochoric process
