PPT-Diffusion

amp Osmosis Why are diffusion and osmosis important Diffusion and osmosis are important because they provide evidence for the existence and movement of particles that is they provide evidence. DIFFUSION: DEFINITIONS. Diffusion is a process of . mass transport. that involves the atomic . or molecular motion. .. In the simplest form, the diffusion can be defined as the . random walk. of an ensemble of particles from regions of high concentration to regions of lower concentration. Diffusion: The motion of atoms through matter. Diffusion Couple: An assembly of two materials in such intimate contact that each diffuse into each other. Ficks. First law of Diffusion:. The flux of diffusing species is proportional to the concentration gradient. A study in semiconductor physics. Ashley Finger and Dr. Tim Gfroerer. Davidson College. Introduction.
