Study Notes
Diffusion
- Movement of particles from an area of high concentration to low concentration.
- Driven by random movement of particles.
- Movement occurs down a concentration gradient.
Factors Affecting Diffusion Rate
-
Temperature: Higher temperature increases diffusion rate.
- Higher temperature leads to increased kinetic energy of molecules.
- Example: Holding a tube of alcohol in your hand increases diffusion rate as the alcohol molecules gain heat.
