Definition Of Diffusion In Physics

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.

Definition of diffusion in physics. Diffusion is a result of the kinetic properties of particles of matter. The cause of diffusion is the thermal motion of particles atoms molecules ions etc. 3 1 the physics of diffusion diffusion is the kinetic process that leads to the homogenization or uniform mixing of the chemical components in a phase. Diffusion is the movement of particles move from an area of high concentration to an area of low concentration until equilibrium is reached.

How to use diffusion in a sentence. This implies that the diffusion theory may show deviations from a more accurate solution of the transport equation in the proximity of external neutron sinks sources and media interfaces. The process of diffusing or the condition of being diffused. The diffusion equation can therefore not be exact or valid at places with strongly differing diffusion coefficients or in strongly absorbing media.

The action of diffusing. The academic definition of diffusion is. Diffusion in the process of diffusion of a single solute a concentration of molecules on one side of a membrane top will move through a membrane center until there is equilibrium on both sides bottom. Diffusion is the mutual penetration of the molecules of one substance into the intermolecular spaces of another substance due to their chaotic motion and collision with each other what cause diffusion.

The solution of diffusion equation let assume the simplest diffusion equation usually starts by division of entire equation by diffusion coefficient. The particles will mix until they are evenly distributed. A familiar example is the perfume of a flower that quickly permeates the still air of a room. Diffusion may also be thought of as the movement of particles down a concentration gradient.

During solution of the diffusion equation we often meet with very important parameter that describes behavior of neutrons in a medium. The diffusion of new technology around the. Diffusion is the movement of a fluid from an area of higher concentration to an area of lower concentration. 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.

Diffusion definition is the state of being spread out or transmitted especially by contact. A distinguishing feature of diffusion is that it results in mixing or mass transport without requiring bulk motion. Diffusion length of neutron.
