    At what temperature, the \[rms\] velocity of \[S{{O}_{2}}\] be same as that of \[{{O}_{2}}\] at\[303\,\,K\]?

    A) \[273\,\,K\]                       

    B) \[606\,\,K\]

    C) \[303\,\,K\]                       

    D)  \[403\,\,K\]

    Correct Answer: B

    Solution :

    \[\frac{{{U}_{rms}}(S{{O}_{2}})}{{{U}_{rms}}({{O}_{2}})}=\sqrt{\frac{T(S{{O}_{2}})}{M(S{{O}_{2}})}\times \frac{M({{O}_{2}})}{T({{O}_{2}})}}\]\[i.e.,\]         \[1=\sqrt{\frac{T(S{{O}_{2}})}{64}\times \frac{32}{303}}\]or                \[T(S{{O}_{2}})=606\,\,K\]
