Diffusion

Definition

Diffusion is a passive process where particles spread out from an area of high concentration to an area of low concentration until equilibrium is reached.

Related terms

Concentration Gradient:

The difference in concentration between two areas. Particles will naturally move from an area with higher concentration to one with lower concentration through diffusion.

Passive Transport:

This refers to movement across cell membranes that does not require energy, such as diffusion.

Equilibrium: A state where concentrations are equal across a system, often achieved through processes like diffusion.
