Diffusion and Fick's Law

Om kurset

Summary This video uses a simple model to help students understand the fundamental difference between a regular and a random walk. The concept of a random walk is connected to diffusion and is used to explain the structure of Fick’s law. Finally, Fick’s Law is used to explain why wearing a coat is useful in the winter, to estimate diffusion times for biomolecules, and to understand why we need a circulatory system to efficiently transport oxygen throughout the body. Learning Objectives After watching this video students will be able to: Describe the difference between regular and random walks. Explain the structure of Fick’s law.
