Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)

The domain of fundamental knowledge in thermodynamics, such as: terminology in the area of
thermodynamics, properties of pure compressible substances, first law of thermodynamics applied to closed and open systems, the second law of thermodynamics, entropy, main thermodynamic cycles.

At the end of the course the student should know how to create models for problem solving, apply thermodynamic properties and perform mass and energy balances, identify the environment that surrounds the physical phenomena related to thermodynamics, perform calculations in various systems of units, working in groups and produce reports.

Demonstration of the syllabus coherence with the UC intended learning outcomes

The contents are based directly upon the objectives.

Teaching methodologies

The curricular unit understands theoretical-practical lessons and the execution of laboratories works. In the assessment are provided 4 modules to perform in person in the Moodle platform during the laboratorial classes or supervised with the respective professor.

Demonstration of the teaching methodologies coherence with the curricular unit's intended learning outcomes

The matter is presented in the theoretical-practical lessons and the concepts illustrated and tested in many exercises and laboratory work. The students equally make use of tests of preparation in the platform e-learning Moodle. The bibliography is also an important support, given its didactic nature, assertive with classes, with abundant examples and with a broad set of exercises to practice.

Assessment methodologies and evidences

The approval in the modules form or by examination is obtained with 10 values. The final score in the modules form is the weighting:
Module 1 (pond 15%): Units and introdutory concepts;
Module 2 (pond 27.5%): Thermodynamic proprieties;
Module 3 (pond 35%): Fist law;
Module 4 (pond 22.5%): Second law, entropy ans cycles.
Students who use modules repeat the procedure and they will no have access to the nomal period of
examination, because this corresponds to the objectives of the examination of the normal season.
Weighted average of the tests*75%+NLaboratory*25% or Examination mark*75%+NLaboratory*25% (including time feature and special time).
