    One mole of a perfect gas expands isothermally to ten times of its original volume. The change in entropy is

    A)  0.1 R         

    B)  2.303 R

    C)  10.0 R        

    D)  100.0 R

    Correct Answer: B

    Solution :

     \[\Delta S=2.303\,nR\,\log \frac{{{V}_{2}}}{{{V}_{1}}}\] \[n=1\] \[\therefore \] \[\Delta S=2.303R\log \frac{10}{1}\] \[\Delta S=2.303R\] \[(\because \,log\,10=1)\]
