Objetivos

The curricular unit has the main goal that student acquire knowledge and competences in the thermodynamic area, being these essentials contents for some others curricular units specific for biotechnology area

Resultados de aprendizagem e competências

It is essential that the students understand and predict physical properties of ideal and real gases, knowing how to apply the three laws of thermodynamics in biochemistry reactions, allowing them to predict and calculate heat changes, entropy variations and spontaneity of the processes.

The student must be able to interpret phase diagram of pure substance, understanding the meaning of triple and critic points, and also to interpret different phase diagrams for mixtures, establishing the basis for several industrial separation process.

It is also necessary that student understand the differences between ideal and real liquid mixtures and the importance of the activity coefficients concept, allowing them to control the variables that affect the equilibrium.

Métodos de ensino e atividades de aprendizagem

In theoretical classes fundamental concepts are exposed. Illustrative applications of these concepts are solved. In theoretical/practical classes, students solve application exercises individually.

In the same semester there is a laboratory associated curricular unit in which the students will perform several experimental works that will exemplify the thermodynamics principles applications.
