    During an experiment, an ideal gas is found to obey an additional law \[\text{V}{{\text{p}}^{\text{2}}}=\]constant. The gas is initially at temperature T and volume V. When it expands to a volume 2V, the temperature becomes

    A)  T                                            

    B)  2 T

    C)  3 T                                        

    D)  T/2

    Correct Answer: B

    Solution :

                     Given, \[V{{p}^{2}}=\] constant                                 \[V{{\left[ \frac{RT}{V} \right]}^{2}}=\] constant                                 \[\frac{{{T}^{2}}}{V}=\] constant                                 \[\frac{{{T}_{1}}^{2}}{{{T}_{1}}^{2}}=\frac{V}{V}=\frac{2V}{V}=2\]
