Question

Consider separate 1.0-L samples of He(g) and UF6(g), both at 1.00 atm and containing the same number of moles. What ratio of temperatures for the two samples would produce the same root mean square velocity?

Answer 1

What you need to know is that average kinetic energy <1/2 m v^2> is proportional to kT, where T is the absolute temperature.
