Molecular diffusion - Wikipedia
Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles.
Molecular Diffusion - an overview | ScienceDirect Topics
Molecular diffusion is a fundamental physical process, caused by the random motion of molecules in gases and liquids, occurring even in completely stagnant conditions. The effect of this random motion is to reduce gradients in concentration, leading eventually to an even distribution of, for example, dissolved chemicals in water.
Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher concentration to one
12.4: Molecular Diffusion - Chemistry LibreTexts
Molecular diffusion is the thermal motion of molecules at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size and shape of the particles.
5.4: The Kinetic-Molecular Theory, Effusion, and Diffusion
The kinetic molecular theory is a simple but very effective model that effectively explains ideal gas behavior. The theory assumes that gases consist of widely separated molecules of negligible …
Diffusion: Definition and How Does it Occur (with Diagram)
Nov 21, 2023 · Diffusion is defined as the movement of atoms, ions, and molecules from a region of high concentration to a region of low concentration, or ‘down their concentration gradient’. The word ‘diffusion’ is derived from the Latin word, ‘diffundere’, meaning ‘to spread out’. Diffusion
10.8: Molecular Effusion and Diffusion - Chemistry LibreTexts
Diffusion is the gradual mixing of gases to form a sample of uniform composition even in the absence of mechanical agitation. In contrast, effusion is the escape of a gas from a container through a tiny opening into an evacuated space.
12.7: Molecular Transport Phenomena- Diffusion, Osmosis, and …
Diffusion is the movement of substances due to random thermal molecular motion. The average distance \(x_{rsm}\) a molecule travels by diffusion in a given amount of time is given by \[ x_{rsm} = \sqrt{2Dt},\] where \(D\) is the diffusion constant, …
Molecular Diffusion - an overview | ScienceDirect Topics
Molecular diffusion is the movement of a solute from an area of greater concentration to lower concentration. This can occur even in the absence of groundwater movement and can be considered a consequence of random molecular motions.
12.9: Diffusion - Physics LibreTexts
Molecular diffusion, often called simply diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles.
