Diffusion is the process where molecules or particles move from an area of higher concentration to an area of lower concentration, resulting in the equal distribution of the substances. It plays a crucial role in various biological and physical processes, such as the exchange of gases in the lungs and the movement of nutrients into cells.
In diffusion, movement of particles across a membrane is driven by differences in concentration gradients, which is the difference in concentration of a substance on either side of the membrane. Particles naturally move from areas of higher concentration to areas of lower concentration until equilibrium is reached.
The process by which gases take the shape of their container is diffusion, in which the gas particles move from an area of higher concentration to an area of lower concentration, until a dynamic equilibrium is reached.
Diffusion depends on where the higher and lower concentrations of solutes are (molecules move from high to low concentration), what kind of membrane (if any) the molecules are moving through, and in many cases how large and charged the molecules are.
cultural diffusion from several countries have ended up in the US because of our diversity and freedom
in mammals, where there is a synapse, a chemical is diffused across the gap between the neurones. :)
