  • question_answer
    The two gases\[{{O}_{2}}\]and\[{{H}_{2}}\]have same temperature at TK. Mean kinetic energy of molecules of\[{{O}_{2}}\] compare to mean kinetic energy of molecule of\[{{H}_{2}}\]will be

    A)  16 times         

    B)  8 times

    C)  equal           

    D)  1/6 times

    Correct Answer: C

    Solution :

     The mean kinetic energy\[E=\frac{3}{2}RT\] or \[E\propto T\] The mean kinetic energy depends upon the temperature. So, the mean kinetic energies will be same for both gases.
