Evaporation Physics: Kinetic Theory of Gases

This lecture covers the fundamental concepts of evaporation physics, focusing on the kinetic theory of gases, the Schrage equation for evaporation, and the diffusion-limited and kinetically-limited aspects of evaporation. The instructor explains the crash course on the kinetic theory of gases, the assumptions related to macroscopic quantities and microscopic molecular motion, and the derivation of the Schrage equation. The lecture also delves into Fick's Law of Diffusion, the physical meaning of gradient and divergence operators, and the coffee ring effects. Additionally, it explores the Maxwell-Boltzmann distribution, the equilibrium contact angle, and the Cassie-Baxter state.
