Examination methods

Written and oral exam.

Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

Learning outcomes
Upon successful completion of the course, students will be able to:

1. classify state variables in the ideal gas law and thermodynamic theory, process variables as energy forms that pass through the system boundaries and classify internal energy

2. analyse basic thermodynamic processes of an ideal gas using a mathematical model and graphical diagrams

3. formulate input and outcome amounts of energy during thermodynamic processes, changing the state variables and internal energy

4. propose the possibility of engineering influence on increasing efficiency degree of circular thermodynamic cycle

5. compare thermodynamic ideal gas processes to water or water vapor as a working medium processes

6. interpret the acquired knowledge in the thermodynamic analysis of the basic processes in a real power plant
