Fick's Law

Fick’s Law describes how particles, like gases or liquids, move from areas of high concentration to areas of lower concentration. This process, called diffusion, depends on how much of the substance is present, how easily it moves through a medium, and the distance it needs to travel. Essentially, it quantifies the rate at which diffusion occurs, indicating that the greater the concentration difference and the easier it is for particles to pass through, the faster the diffusion. This principle helps explain processes like oxygen moving into the blood or how scent spreads in the air.
