    The dimensions of universal gas constant is?                                                   [Pb. PET 2003]

    A)             \[[M{{L}^{2}}{{T}^{-2}}{{\theta }^{-1}}]\]

    B)               \[[{{M}^{2}}L{{T}^{-2}}\theta ]\]

    C)             \[[M{{L}^{3}}{{T}^{-1}}{{\theta }^{-1}}]\]

    D)               None of these

    Correct Answer: A

    Solution :

                    \[\because R=\frac{PV}{T}\]\[=\left[ \frac{M{{L}^{-1}}{{T}^{-2}}\times {{L}^{3}}}{\theta } \right]=[M{{L}^{2}}{{T}^{-2}}{{\theta }^{-1}}]\]
