PPT-Diffusion Experiment

Question How does temperature effect the rate of diffusion Hypothesis Test See how long it takes for a drop of food coloring to diffuse at different temperatures Chart Setting Diffusion Time. 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 1. Diffusion Ordered Spectroscopy. Provides a way to separate different compounds in a mixture based on the differing translational diffusion coefficients (differences in the size and shape of a molecule). Overview. Theory.

This means diffusion moves down the concentration gradient, i.e., from high to low concentration.. Deriving Fick’s Law. and Osmosis. Diffusion . is the movement of particles from an area of high concentration to an area of low concentration. When a particle moves from an area of high concentration to an area of low concentration, it is said that it is moving down its . WHAT IS CULTURE??. 2. 3. Culture.

Cette présentation a été réalisée dans le cadre de notre formation en licence professionnelle plasturgie ; elle résulte de la synthèse des sources (Cf. fin de présentation) que nous avons pu trouver, et nous ne pouvons en aucun cas être tenu responsable des éventuelles erreurs techniques.. 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.. . SIMPLE DIFFUSION. WHAT IS DIFFUSION. Diffusion is the movement of molecules or particles from a region of high concentration to a region of low concentration. . . Essential Question. How does the spatial diffusion of ideas, products, and traits lead to change, including cultural divergence and convergence?. 1. A process of spatial exchange in which ideas, products, cultural traits and even diseases spread from one place to another..
