    The r. m. s velocity of a gas at a particular temperature is found to be 12240 cm \[{{\sec }^{-1}}.\]What is its most probable velocity (in cm \[{{\sec }^{-1}}.\]) at the same temperature?

    A)  \[{{10}^{5}}\]                                   

    B)  \[{{10}^{4}}\]

    C)  11280                                  

    D)  1128

    Correct Answer: B

    Solution :

                     Given, rms velocity \[=12.240\,\text{cm }\,\text{se}{{\text{c}}^{-1}}\] Most probable velocity= \[\text{= 0}\text{.816  }\!\!\times\!\!\text{  rms}\] velocilty \[=0.816\times 12,240\] \[=9987.84\,\text{cm se}{{\text{c}}^{-1}}\] \[\approx \,10,000\]or \[{{10}^{4}}\]
