Diffusion: The Movement of Particles in Liquids and Gases

This is a lecture presentation on diffusion, where the process of diffusion of particles in liquids or gases is explained in terms of kinetic particle theory. The presentation incorporates a mixture of two liquids and a demonstration experiment of the diffusion of vapors of ammonia and hydrochloric acid. The video also discusses the factors that affect the rate of diffusion and how the molecular mass of a molecule affects its diffusion rate.
