Moleculesdiffuse
Moleculesdiffuse is the term used to describe the process by which molecules spread within or between media due to random thermal motion, moving from regions of higher concentration to regions of lower concentration. It operates in gases, liquids, and solids, with rates that depend on temperature, molecular size, and the properties of the surrounding medium.
The rate and direction of diffusion are described by Fick's laws. Fick's first law states that the
Factors affecting diffusion include temperature (higher T generally increases D), molecular size and shape, solvent viscosity,
Applications span drug delivery, environmental transport of pollutants, food science, materials engineering, and soil science. Measurement
