Subject provides basic information on methods of measurements of selected physico-chemical quantities. Selected quantities (temperature, pressure, volume/density, thermal quantities) are basic quantities needed as input for classical thermodynamics employed for evaluation of non-measurable thermodynamic properties of systems.

1. Processing of experimental data - uncertainty propagation, uncertainty of regression parameters. Current international temperature scale (ITS 90). 2. Definition of thermodynamic temperature and its units, black-body radiation, thermometric properties. 3. Methods for accurate measurements of temperature: resistance thermometers, thermocouples, etc. Dynamics of simple heat systems: thermometer, thermostat. 4. Thermal analysis: thermogravimetry, dielectric and mechanical spectroscopy. 5. Measurement of heat effects: differential scanning calorimetry, heat pulse calorimetry, etc. 6. Construction and calibration of calorimeters. Choice of calibration standards. 7. Processing of calorimetric data: temperature of phase transition, heat effect, heat capacity, etc. Identification of reversible and irreversible processes. 8. Examples of the interpretation of experimental measurements: polymorphism, phase diagrams, etc. 9. Purification and purity measurement. Concept of pressure. Pressure generation, pressure standards. 10. Measurement of pressure, mechanical and electrical transducers, standards. Vacuum. Vacuum generation, vacuum pumps, and measurement of low pressures. 11. Classification of methods for measurements of volumetric properties, analysis of factors affecting density (temperature, pressure, purity, isotopic composition). 12. Direct methods for liquids, examples of devices for PVT measurements. Methods for measurements of state behaviour of gases and solid substances. 13. Indirect methods for liquids (vibrating-tube densimeter, buoyancy methods, speed-of-sound methods). 14. Laboratory exercises: Differential Scanning Calorimetry, calibration of thermometers, triple point of water, setting and properties of a simple thermostat. Last update: Vopička Ondřej (13.06.2025)

After passing successfully the subject a student should have an overall knowledge on methods for measurement of temperature, pressure, volume/density, and thermal properties. In practice he/she should be able to select a proper method for a particular conditions and requirements. Last update: Pátková Vlasta (15.01.2018)
