Physics 212 Lecture: "Diffusion."
Jan 16, 1998
- Diffusion is the process by which a fluid material (solute)
spreads out through a static medium (solvent)
- Individual particles in the solute bounce off particles
in the solvent, resulting in a "random walk"
- Diffusion is similar in some respects to the conduction of heat:
both involve large-scale changes caused by small-scale
interactions of neighboring particles
- Fick's law for diffusion is similar to the heat conduction equation
This lecture discusses material in Chapter 14 of Cutnell and Johnson.
