Course objectives

The course of Thermodynamics covers the basics of general thermodynamic principles and their application in engineering. The goal is for students to master the knowledge of basic thermodynamic principles and their application in engineering, which will be helpful in their further studies as well as in their work.

Course enrolment requirements and entry competences required for the course

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After passing the exam, students are expected to:
- specify and define the units of measurements of basic thermodynamic magnitudes and the state equation
- specify and correctly interpret the basic laws of thermodynamics
- specify and explain thermodynamic changes of the state of ideal gases
- define and explain the processes of expansion and compression
- define and explain cycles processes
- define and explain irreversible processes (throttling, mixing of gases)
- specify and describe heat properties and changes of the state of real gases
- discern and analyse processes in devices used to obtain low temperatures
- define thermodynamic properties of moist air and processes with moist air
- apply the knowledge acquired to solving tasks related to changes of the state of ideal and real gases and liquids, compression processes, cycles processes, processes in devices used to obtain low temperatures and processes with moist air.
