Teaching method

The BioThermodynamics curricular unit is divided into the following components: Theoretical (T); Theoretical-Practical (TP) ; and in a practical component (P). The theoretical classes, T, have a duration of 2.5 hours per week (1 hour + 1:30 hours) and the TP classes of 0,5 hour per week (1 hour every two weeks). Laboratory classes, P,  have a workload of two hours per week.

The T classes serve to introduce students to the structural content of the Thermodynamics as a fundamental area. In TP classes, a discussion and resolution of exercises apply the concepts exposed in the Ts. In P laboratory classes, experimental work is carried out with the aim of verifying physical phenomena or processes described in the theoretical-practical classes and to develop laboratorial skills as well as handling relevant equipment.

General information about this discipline, such as rules, important dates, evaluation notes and other complementary information are available on the course''s page in the CLIP. Documentation necessary for the realization of practical classes should be consulted in the CLIP in the folder “Protocols”. Contents and Bibliography, are also available on CLIP.
