(a) The liquid and gaseous state of chlorine are in thermal equilibrium at 239 K. Even though it is on the point of condensation, model the gas as ideal and determine the most probable speed of the molecules (in m/s). m/s (b) What If? At what temperature (in K) would an atom of radon in a canister of radon gas have the same most probable speed as the chlorine in thermal equilibrium at 239 K? K
