    The volume of one mole of an ideal gas changes from V to 2 V at temperature 327°C. If R is the universal gas constant, then the work done in this process is

    A)  300 R In 2                           

    B)  600 R In 2

    C)  300 In 2                                               

    D)  600 In 2

    Correct Answer: B

    Solution :

                     Work done in an isothermal process \[W=\mu RT{{\log }_{e}}\frac{{{V}_{2}}}{{{V}_{1}}}\] \[=1\times R\times (273+327){{\log }_{e}}=\frac{2V}{V}\] \[=600R\,\,\,in\,\,2\]
