Diffusion in Gases, Liquids, Solids

This lecture covers the diffusion coefficient in gases, liquids, and solids, including the Matano method, atomic theory of diffusion, cubic crystals, random movement, and interstitial movement. It explores examples of cubic crystals, the general theory of random movement, and interstitial movement. The lecture also delves into the diffusion coefficient in gases, discussing the factors influencing diffusion, such as temperature, molecular weight, molar fraction, pressure, and collision diameter. It further examines the semi-empirical equation for diffusion in gases, the influence of temperature, molecular weight, and pressure, and the determination of collision diameter. The lecture concludes with the diffusion coefficient in gases, the equation for diffusion in gases, and the influence of various parameters on diffusion.
