Thermodynamics

Recommended Prerequisites

The student must review the basic physical and mathematical concepts learnt in secondary school courses. These should be complemented, in mathematics, with knowledg concerning primitive and derived forms of current functions, as well as the ability to carry out calculations of defined integrals (contents that are leanrt in Mathematical Analysis I and II). The reviewed physical concepts should be complemented with notions concerning the definitions of units, mechanics and calorimetry (also learnt in General Physics Course I). The student should have basic knowledge of English.

Teaching Methods

The lectures consist of the oral presentation of the most important aspects of the summarized matters - the student will be able to deepen through the study of recommended literature, accompanied by the teacher during office hours posted at the beginning of each semester. The practical classes allow the study of specific applied problems with quantitative solutions.

Learning Outcomes

The discipline of thermodynamics mainly implies: the review and clarify the knowledge already acquired in Classical Mechanics and systems of units; the understanding of thermodynamics as fundamental science; develops and implements the basic ideas of heat, work and the properties of materials, demonstrated by engineering problems that help to develop creativity and motivation; developd physico-chemical models , which associated with an experimental approach , increase the understanding of the concepts and formalism of this discipline; Provide students with the information necessary for obtaining quantitative solutions of practical problems and sensitize them to the choice of justified criteria for their resolution; Initiate the student to the experimental techniques that are associated with thermal phenomena.

This discipline differs, from that is usually taught in courses in Physics and Chemistry, for applied engineering problems with quantitative solutions.

Syllabus

The syllabus consists of the study of the phenomenological thermodynamics of closed systems, associated to the systems of gases and condensed phases.

1. The fundamental concepts ( parameters , states , state functions ; stationary states and equilibrium ; Zero Law of Thermodynamics; temperature and thermometric scales ; thermodynamic processes or transformations).

2. The First Law of Thermodynamics. Internal energy (work , heat and statement of the First Law ). Consequence. Enthalpy ( definition and general expression )

3. Characteristical equations of state and thermal energy.

4. The Second Law of Thermodynamics. Statement of the Second Law. Exchanges and entropy production

5. The Third Law of Thermodynamics. Justification of the Third Law. Statement of the Third Law and comments. Impossibility of reaching absolute zero - applications

6. Characteristic functions of state and application examples.

7. Thermodynamic diagrams.

8. Humidity; wet air.
