10 Facts About Diffusion

Diffusion is the net movement of anything generally from a region of higher concentration to a region of lower concentration.

Diffusion is driven by a gradient in Gibbs free energy or chemical potential.

Diffusion used Graham's research, stating his goal as "the development of a fundamental law, for the operation of diffusion in a single element of space".

Diffusion asserted a deep analogy between diffusion and conduction of heat or electricity, creating a formalism similar to Fourier's law for heat conduction and Ohm's law for electric current .

Diffusion studied self-diffusion of radioactive isotopes of lead in the liquid and solid lead.

Diffusion coefficient is the coefficient in the Fick's first law, where J is the diffusion flux per unit area per unit time, n is the concentration, x is the position [length].

Diffusion is a property of substances in water; substances in water tend to move from an area of high concentration to an area of low concentration.
