    If at the same temperature and pressure, the densities of two diatomic gases are\[{{d}_{1}}\]and\[{{d}_{2}}\]respectively, the ratio of mean kinetic energy per molecule of gases will be

    A)  \[1:1\]             

    B)  \[{{d}_{1}}:{{d}_{2}}\]

    C)  \[\sqrt{{{d}_{1}}}:\sqrt{{{d}_{2}}}\]        

    D)  \[\sqrt{{{d}_{2}}}:\sqrt{{{d}_{1}}}\]

    Correct Answer: A

    Solution :

     Mean kinetic energy of gas depends only on the temperature. Here temperature is given same, so ratio of kinetic energies will be\[1:1\].
