  • question_answer
    Among the following gases which one has the lowest root mean square velocity at \[{{25}^{o}}C\]           [EAMCET 1983]

    A)                 \[S{{O}_{2}}\]   

    B)                 \[{{N}_{2}}\]

    C)                 \[{{O}_{2}}\]     

    D)                 \[C{{l}_{2}}\]

    Correct Answer: D

    Solution :

                    Among these \[C{{l}_{2}}\] has the highest molecular weight so it will posses lowest root mean square velocity.
