Diffuusioprosessi refers to the process of diffusion. Diffusion is the net movement of anything generally from a region of higher concentration to a region of lower concentration. The driving force for diffusion is the random motion of molecules. In physics, it is the random movement of particles that causes them to spread out from a region where they are concentrated to a region where they are less concentrated. This process occurs in gases, liquids, and even solids, although at significantly different rates.

In biology, diffusion plays a crucial role in cellular processes. For example, oxygen and carbon dioxide move across cell membranes by diffusion, as do many nutrients and waste products. The concentration gradient dictates the direction of movement. This passive transport mechanism does not require energy input from the cell.

In chemistry, diffusion is responsible for the mixing of substances. When you add a drop of ink to water, the ink molecules gradually spread out and mix with the water molecules due to diffusion. The rate of diffusion is influenced by factors such as temperature, the size of the diffusing particles, and the medium through which they are diffusing. Higher temperatures generally lead to faster diffusion because molecules have more kinetic energy and move more rapidly. Similarly, diffusion is faster in gases than in liquids, and faster in liquids than in solids. Understanding diffusion is fundamental to many scientific disciplines.
