    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. \[\text{(}\Delta \text{E =}\,\text{0)}\] [b] \[\Delta q=0-\text{Adiabatic}\,\text{process}\] [c]\[\Delta V=0-\text{Isochoric}\,\text{process}\]
