A simplified way to understand this concept is to imagine a crowded subway train in New York City. Diffusion -the process by which molecules spread from areas of high concentration, to areas of low concentration. When the molecules are even throughout a space - it is called EQUILIBRIUM Concentration gradient- a difference between concentrations in a space. The term is most commonly used to describe the process by which molecules of different types achieve a uniform concentration, after initially being unevenly distributed, through their random movements. This is sometimes called molecular diffusion and it plays a key role in many areas of physics, chemistry, and biology. The textbook definition of diffusion is the movement of molecules or particles from an area of higher concentration to an area of lower concentration, continuing until equilibrium is reached.

"This cartoon illustrates passive diffusion. The process of simple diffusion is applied in the action of medicines in the body. Once a medicine is ingested, the molecules are released into the respective sites of action through the process of simple diffusion. Air pollution is another phenomenon that is a result of diffusion. Diffusion-controlled (or diffusion-limited) reactions are reactions in which the reaction rate is equal to the rate of transport of the reactants through the reaction medium (usually a solution). The process of chemical reaction can be considered as involving the diffusion of reactants until they encounter each other in the right stoichiometry Diffusion is the spreading of the particles of a gas, or of any substance in solution, resulting in a net movement from a region where they are of a higher concentration to a region with a lower concentration. Imbibition is a reversible process whereas diffusion is an irreversible process.

Simple diffusion – A process of diffusion that occurs without the aid of an integral membrane protein. Allows substances to pass through cell membranes without any energy.

When the molecules are even throughout a space - it is called EQUILIBRIUM Concentration gradient- a difference between concentrations in a space. Molecules will always move down the concentration gradient, toward areas of lesser concentration. The movement of various substances into a plant, usually from the soil, out of which the green plant synthesises the numerous complex organic compounds, is accomplished, principally through the agency of the process known generally as diffusion. Diffusion is the net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration.

let's say that I have this green container and inside this green container I have some air molecules now the air molecules we assume that there's some temperature there's some average kinetic energy to them but they're all going to have different velocities they're all going to be bumping around in different ways now the way that I've drawn it you might notice something on the left-hand side

It is an important process occurring in all living beings. Diffusion helps in the movement of substances in and out of the cells. Diffusion is a process at the molecular level and is determined by the random nature of the movement of individual molecules. It is the process of the net passive movement of particles from a higher concentration area to a lower concentration area in any mixture. It follows a downhill concentration gradient. Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. Passive diffusion is the movement of molecules across a membrane, such as a cell membrane.

Medium: Diffusion can take place in all mediums (solid, liquid, and gas). Osmosis only occurs in a liquid medium. Type of diffusing molecules: The moving molecules can be either of solid, liquid or gases. The moving molecules in osmosis are always liquid molecules.

For example, think about someone opening a bottle of ammonia in a room filled with people. Diffusion is also relevant to the movement of microorganisms and nutrients through slimes and gels in natural ecosystems. Of course, in microbiology there are practical applications of diffusion, such as the assay of antibiotic concentrations, in which diffusion, among other factors, controls the size of the zone of inhibition.
