Learning outcomes |
Lectures explane statistical nature of basic thermodynamic quantities (thermal energy, entropy, temperature) and thermodynamic laws of energy conversion and increase of entropy. Probability interpretation of entropy establishes a bridge between macroscopic quantities and microscopic quantum-mechanical description of matter. Besides usual investigation of thermodynamic properties of gases and simple solids, low and negative temperatures are examined, as well as phase transitions in ferroelectric and superconducting materials and fluctuations, which are illustrated by computer simulations.
