    Helium atom is two times heavier than hydrogen molecule. At 298 K, the average kinetic energy of helium atom is

    A)  two times that of hydrogen molecule

    B)  same as that of hydrogen molecule

    C)  four times that of hydrogen molecule

    D)  half that of hydrogen molecule

    Correct Answer: B

    Solution :
