    At what temperature the RMS velocity of \[S{{O}_{2}}\] be same as that of \[{{O}_{2}}\] at 303 K              [KCET 2001]

    A)                 273 K    

    B)                 606 K

    C)                 303 K    

    D)                 403 K

    Correct Answer: B

    Solution :

      \[\frac{{{U}_{S{{O}_{2}}}}}{{{U}_{{{O}_{2}}}}}=\sqrt{\frac{{{M}_{{{O}_{2}}}}{{T}_{S{{O}_{2}}}}}{{{M}_{S{{O}_{2}}}}{{T}_{{{O}_{2}}}}}}=\sqrt{\frac{32\times }{64\times }\frac{{{T}_{S{{O}_{2}}}}}{303}}=1\]                                 \[1=\frac{32\times }{64}\frac{{{T}_{S{{O}_{2}}}}}{303}\] Þ \[{{T}_{S{{O}_{2}}}}=606\]
