Problem 4: A bottle of perfume is opened in a room in which the air is perfectly still. Assume Dperfume = 5 x 10-6m²/s. Estimate the time t that it will take for the perfume molecules to diffuse a distance L=5 m across the room. Don't be surprised if the time is very long. Diffusion is very slow. Almost always, gases mix due to stirring or convection, long before diffusion mixes them.

The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed 3 RT rms speed %3D where R = 8.314 J/(mol-K) and M is molar mass in kilograms per mole. Note that a joule is the same as a kilogram-meter squared per second squared (kg-m²/s²). What is the rms speed of O, molecules at 411 K? rms speed: m/s What is the rms speed of He atoms at 411 K? rms speed: m/s
