Learning and Teaching Methods
In the thematically structured lecture the learning content is presented.
In the Tutorial the learning content is deepened and exercised using problem examples and calculations. Additionally in scientific discussions the analyticphysics intellectual power is stimulated so that the students are able to explain and apply the learned physics knowledge independently.

Module Exam
Description of exams and course work
There will be an oral exam of about 60 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions and sample calculations. Especially important is to prove that she/he has realised the correlation between different topics in thermodynamics and is able to explain this in a comprehensive manner. In an (developing) oral exam this can be proved in the most efficient way.
For example an assignment in the exam might be:
 What is the first law of thermodynamics?
 How is entropy calculated in statistics physics and what is the meaning of it?
 What kind of statistics must be used to describe an electron gas?
Exam Repetition
The exam may be repeated at the end of the semester.
