Chemistry is the science that focuses on matter in its broader sense, having a wide system of concepts. It is different, for instance, from mineralogy or from pharmacy. The concepts of Chemistry are generically applied to the empirical world, explaining it. And this, because Chemistry in its nucleus continues to investigate systematically the specific relational structure of the chemical estates and of the chemical substances, which decides the logical structure of the chemical knowledge in all its cognitive levels.
This course unit of introductory level aims at developing and highlighting the relation between the estates of the chemical systems to the macroscopic scale (resultant of the observation) and to the microscopic level (necessary to the interpretation of the phenomena). The specification of this general objective is only possible through the understanding of fundamental concepts of thermodynamics, kinetic and structure of the matter. These concepts, that naturally are part of other scientific disciplines, where will occasionally be deepened according to the requirements of the respective areas, allow the construction of a solid base of scientific knowledge.
