PPT-Diffusion

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. What is chemical diffusion coefficient and tracer diffusion coefficient How are they inter related as D 1 ln ln Understand the meaning of th thermodynamic factor 1 ln ln and the relationship with the free energy gradient 1 ln ln 1 ln ln in SPH and grid codes.

Fick’s First Law. Last time we introduced Fick’s First Law. Note minus sign. This means diffusion moves down the concentration gradient, i.e., from high to low concentration.. Deriving Fick’s Law. Molecules are always moving. Molecules move randomly and bump into each other and other barriers. Concentration gradient. Concentration Gradient - change in the concentration of a substance from one area to another.. Calisthenics: . BIG QUESTIONS. Big Word of the Week:. Cultural Diffusion. Big question of the Day:.
