Dynamic, statistical and thermodynamic methods of studying matter

Three methods of describing many-particle systems — dynamic, statistical and thermodynamic; macroscopic and microscopic parameters, thermodynamic equilibrium, temperature and the characteristic features of microscopic systems.

Estimated time: 3 h 4 activities

Learning objective

Understand the essence, possibilities and limitations of the dynamic, statistical and thermodynamic methods.
Distinguish macroscopic and microscopic parameters.
Learn the concepts of a thermodynamic system, equilibrium state, relaxation and quasi-static process.
Realise the role of statistical regularities and fluctuations in many-particle systems.

Expected outcomes

Justifies which problems each method suits best.
Quantitatively estimates why the dynamic method is practically inapplicable to many-particle systems.
Calculates the relative fluctuation using the $1/\sqrt N$ law.
Converts temperature between scales and finds the mean kinetic energy of a molecule.
