Learn advanced thermodynamics concepts in this MIT OpenCourseWare lecture focusing on the minimum work required for partitioning small systems, equilibrium properties of pure substances, and the Gibbs phase rule. Explore the Clausius-Clapeyron relation and its representation across various diagrams including p-T, u-v-s, h-s, and p-v. Delve into the van der Waals model of metastable liquid and vapor states through comprehensive coverage of topics ranging from microscopic and mesoscopic systems to extensive and intensive properties. Master fundamental concepts like the Euler relation, rarefaction effects, and simple-system models for pure substances. Examine practical applications through detailed discussions of ideal incompressible solids, fluid models, and two-phase states. Conclude with insights into exergies, efficiencies in energy conversion, and bulk flow interactions. The instructor recommends viewing at 1.5x speed for optimal learning efficiency.
