WebDefinition. Diffusion is defined as intermixing two or more gases at a given temperature, and pressure. It is random movement from the region of higher pressure to lower pressure along the concentration gradient. Concentration gradient is defined as concentration per unit length. Diffusion occurs in liquids and gases but hardly in solid. WebAug 18, 2024 · The kinetic molecular theory of gases gives a reasonably accurate description of the behavior of gases. A similar model can be applied to liquids, but it must take into account the nonzero volumes of particles and the presence of strong intermolecular attractive forces.
