Elective
1st Cycle Studies
Recommended Prerequisites
Secondary school Chemistry (preferably 12th year) and basic English.
Teaching Methods
Teaching is based on lectures, encouraging student participation and discussion of topics, and exercice-solving classes aimed at analysing and obtaining the solution for problems while encouraging, once again, the participation of students, now gathered in smaller groups.
Learning Outcomes
This course provides the foundations to be developed along the course in later issues.
Establishes the scales (from microscopic to macroscopic) of the relevant systems, and defines, in a simple way, their relationship.
Promotes a reasoning aiming at integrating complementary subjects.
