The aim of the course is to understand and quantify structure, motion and interactions at the molecular level in gaseous, liquid and solid phases of pure substances and mixtures and to correlate them with macroscopic properties; also, to familiarize students with phase diagrams and interfacial phenomena.

The material covered includes the following: Intermolecular forces. Introduction to Statistical Mechanics.  Heat capacities in the ideal gas state from spectroscopic data . Kinetic theory of dilute gases: Maxwell-Boltzmann distribution of molecular speeds, mean free path, frequency of molecular collisions. Viscosity, thermal conductivity, diffusivity in the gaseous state. Real gases: virial equation of state. Van der Waals equation of state and its predictions for phase equilibria and criticality. Joule-Thomson coefficient. Liquids: vapor pressure, viscosity, surface tension, wetting and spreading, capillary phenomena. Solids: Crystal systems and lattices. Amorphous solids. Heat capacities of solids, elements of Einstein and Debye theories. Multicomponent systems: Partial molar properties. Ideal and real solutions. Colligative properties (vapor pressure reduction, boiling point elevation, melting point depression, osmotic equilibria). Vapor-liquid equilibria, azeotropes. Partially miscible liquids. Solid-liquid phase diagrams in binary systems. Eutectic  points. Ternary mixtures, Gibbs-Roozeboom diagram. Sorption equilibria. Colloids.
