Lecture
This lecture introduces the concepts of phase transitions, stability, and phase diagrams, focusing on the coexistence of phases and the Clausius-Clapeyron equation. It covers topics such as metastable phases, phase coexistence lines, and the Van der Waals gas model. The instructor discusses the behavior of substances under different conditions, illustrating the generation of phase diagrams and the significance of critical points. Various experimental observations related to phase transitions and latent heat are also presented.
