Chemistry

There is no recommended background knowledge.

Theoretical classes aim at the presentation and development of the subjects that constitute the syllabus of the discipline. They are expository classes, following a script based on slides and with frequent use of the blackboard and dialogue with students. In the theoretical-practical classes, problems are presented that aim to consolidate the themes of the theoretical classes, helping students to solve them by themselves.

The objectives of the UC of Chemistry are related to its fundamental role, generalist and pedagogical support. The approach and development aim at its applicability to the study of mechanical engineering. It is intended to provide students with an understanding of the fundamentals of chemistry, creating in students competence to: -Solve simple physicochemical problems, using an appropriate form, without physical units, concentrations, yields or phase changes being a problem; -Identify, interpret and know how to communicate the relationship between microstructure and material properties; -Predict the direction of evolution of chemical systems based on thermodynamic data; -Interpret and communicate the mechanisms involved in the deterioration of metals by electrochemical processes; -Complement and consolidate knowledge of the subjects covered in the UC, being able to access new knowledge through the use of bibliographic material, databases, internet, etc.
