Definition Diffusion And Example

The concept of diffusion is widely used in many fields including physics particle diffusion chemistry biology sociology economics and finance diffusion of people ideas and price.

Definition diffusion and example. One of the classic examples of simple diffusion is the movement of gases across the membrane in animals. Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room. A drop of food coloring diffuses throughout the water in a glass so that eventually the entire glass will be colored.

Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. Diffusion is driven by a gradient in concentration. Similarly the medium in which diffusion occurs could also be in one of the three physical states. The particles suspended in liquids and gases for instance struck each other resulting in their random constant motion.

Simple diffusion is defined as the process in which a substance moves through a semipermeable membrane or in a solution without any help from transport proteins. Diffusion happens in liquids and gases because their particles move randomly from place. State an example of simple diffusion. Diffusion is the net movement of anything for example atom ions molecules from a region of higher concentration to a region of lower concentration.

It follows a downhill concentration gradient. Diffusion in physics is the movement of particles from an area of higher concentration to an area of lower concentration as driven by thermal energy. The material that diffuses could be a solid liquid or gas. Diffusion process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.

1 this definition is affirmed as well in chemistry. It is the process of the net passive movement of particles from a higher concentration area to a lower concentration area in any mixture. Examples of diffusion perfume is sprayed in one part of a room yet soon it diffuses so that you can smell it everywhere.
