A flask contains a mixture of neon (Ne), krypton (Kr), and radon (Rn) gases. Compare
(a) The average kinetic energies of the three types of atoms and;
(b) The root-mean-square speeds. (Hint: The periodic table in Appendix D shows the molar mass (in g/mol) of each element under the chemical symbol for that element)
