Diffusion

 Diffusion could be a physical method that refers to internet movement of molecules from a vicinity of high concentration to at least one of lower concentration. the fabric that diffuses might be a solid, liquid or gas. Similarly, the medium within which diffusion happens may even be in one amongst the 3 physical states.

One of the most characteristics of diffusion is that the movement of molecules on the concentration gradient. whereas this might be expedited by alternative molecules, it doesn't directly involve high-energy molecules like nucleotide (ATP) or nucleoside triphosphate (GTP). The rate of diffusion depends on the character of interaction between the medium and material. for example, a gas diffuses terribly quickly in another gas. associate example of this is often the approach the harmful smell of ammonia gas spreads in air.
