Diffusion: The Movement of Particles in Liquids and Gases

The video tutorial explains diffusion using kinetic particle theory, defining it as the movement of particles from high to low concentration. It illustrates diffusion with a diagram of two liquids mixing and describes an experiment demonstrating the diffusion of ammonia and hydrochloric acid vapors. The experiment shows how ammonium chloride forms due to the reaction of these vapors, highlighting that diffusion rates depend on molecular mass. The tutorial concludes with a summary of key points.

What factors affect the rate of diffusion according to the kinetic particle theory?

How does the random motion of particles contribute to the process of diffusion?
