LEARNING OUTCOMES

Acquiring rigorous methodology to describe as accurately as possible the fundamental phenomena that are the basis of chemical systems; knowing how to understand and use the minimum mathematical formalism required to interpret them.

TEACHING METHODS

Classroom lectures.

SYLLABUS/CONTENT

Thermodynamics

System definition, path definition, definition of state function; enunciation of the three principles

first principle: heat, work, U, definition of H; Joule experience;

isobar, isotherm, cycle Hess, equations of Kirchhoff relationship Mayer;  cycle on the isobaric-isotherm;
