    The temperature of \[3:1\] at which the rms velocity of its molecules is seven times the rms velocity of the molecules of nitrogen at 300 K is

    A)  \[1:9\]                 

    B)  \[1:16\]

    C)  \[6m/s\]                            

    D)  \[4m/s\]

    Correct Answer: D

    Solution :

                     Velocity of the molecules of nitrogen \[3m/{{s}^{2}}\] \[-3m/{{s}^{2}}\] \[0.3m/{{s}^{2}}\] \[7=\sqrt{\frac{{{T}_{H}}\times 28}{2\times 300}}\] \[49=\frac{{{T}_{H}}\times 28}{600}\] \[{{T}_{H}}=\frac{49\times 600}{28}=1050K\]
