Boltzmann constant-A constant, k, involved in the equation for average velocity. k = 1.38Ã10-23 J/K. Diffusion-Diffusion is the spread of one substance through another. Effusion-Effusion is the rate at which a gas passes through a small hole into a vacuum. Kinetic energy-E k = 1/2mv 2. Kinetic molecular theory-A theory that models the interaction between individual gas molecules. See the summary for more details. Maxwell-Boltzmann speed distribution-The distibution attained when molecule speed is set against the number of molecules sharing that speed.
