Diffusion
Bayani Gaba-gaba
Open a bottle of perfume at one side of a room and, a little later, someone on the far side can smell it. No one carried it across; the scent spread by itself. This silent spreading is diffusion, and it is direct evidence that particles are always on the move.
In this lesson you will learn what diffusion is, why it happens, and how the kinetic particle theory explains it. You will also see why gases diffuse faster than liquids, and why lighter particles diffuse faster than heavier ones at the same temperature.
Manufura
- Describe and explain diffusion in terms of kinetic particle theory.
- [Supplement] Describe and explain the effect of relative molecular mass on the rate of diffusion of gases.
