Objetivos

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.

Resultados de aprendizagem e competências

Create models for problem solving; perform calculations and conversions in the different systems of units; understand, distinguish and apply power and energy concepts; perform energy and mass balances and apply thermodynamic properties in these calculations; identify in the surrounding environment the physical phenomena related to thermodynamics (atmospheric phenomena, heat engines, thermal power stations, common equipment (refrigerators, central heating, air conditioning, water heaters, swimming pools).

Métodos de ensino e atividades de aprendizagem

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.
