Description

This lecture introduces the gas-liquid interface, discussing attractive forces between molecules with permanent dipole moments and apolar molecules. It covers the Lennard-Jones potential, curved liquid surfaces, and the Young-Laplace equation for bubbles and droplets. The concept of vapor pressure on curved surfaces, Kelvin equation, and nucleation are explained, along with wetting, contact angle, and surface tension measurements using the Wilhelmy plate and Du Noüy ring methods.
