    The volume of one mole of an ideal gas changes from V to \[2\text{ }V\]at temperature\[{{327}^{o}}C\] If R is the universal gas constant, then the work done in this process is

    A)  \[300\text{ }R\]In 2      

    B)  \[600\text{ }R\]In 2       

    C)  \[300\]In 2        

    D)  \[600\] In 2

    Correct Answer: B

    Solution :

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