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

    A) two times that of hydrogen molecule

    B) same as that of a hydrogen molecule

    C) four times that of a hydrogen molecule

    D) half that of a hydrogen molecule

    Correct Answer: B

    Solution :

    The average kinetic energy of an atom is given as\[\frac{3}{2}\,\,kT\]. \[\therefore \] It does not depend on mass of the atom.
