Evaporation Physics: Part I

This lecture covers the fundamental aspects of evaporation physics, including topics such as equilibrium contact angles, different states of wetting, Cassie-Baxter state, and Wenzel state. It also discusses the evaporation process in air, the diffusion of water vapor, Fick's Law of Diffusion, and the analogy between heat and mass transfer. The lecture concludes with examples of mass transfer correlations, the coffee ring effect, and the sessile droplet shape.
