    \[\alpha \], v and u represent most probable velocity, average velocity and root mean square velocity respectively of a gas at a particular temperature. The correct order among the following is

    A) \[u>v>\alpha \]            

    B) \[v>u>\alpha \]

    C) \[\alpha >u>v\]            

    D) \[u>\alpha >v\]

    Correct Answer: A

    Solution :

    [a] \[u:v:\alpha =\sqrt{\frac{3RT}{M}}:\sqrt{\frac{8RT}{\pi M}}:\sqrt{\frac{2RT}{M}}\] \[=\sqrt{3}:\sqrt{\frac{8}{\pi }}:\sqrt{2}\]
