Diffusion is a process that describes the movement of particles (such as molecules, atoms or ions) from a region of higher concentration to a region of lower concentration. This phenomenon is important in many natural and engineering systems and plays a key role in physics, chemistry, biology and other sciences.

Diffusion is a random process that leads to the equilibration of concentration differences between two regions. The particles move randomly and in this way gradually diffuse from the region of greater concentration to the region of lesser concentration until they balance the difference. This process takes place even when there is no external force acting on the particles.

Diffusion has many practical consequences, for example:

Diffusion in cell membranes is a key process for the transfer of substances into and out of cells.
Diffusion of gas in the lungs allows the exchange of oxygen and carbon dioxide between air and blood.
Diffusion in materials is important for processes such as corrosive wear of metals.
Diffusion in the environment affects the movement of nutrients and pollutants in water and air systems.
