Laws of diffusion
Web3.1 The Physics of Diffusion. Diffusion is the kinetic process that leads to the homogenization, or uniform mixing, of the chemical components in a phase. Although … WebDiffusion In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space. For example, think about someone opening a bottle of cleaning ammonia in the middle of a room.
