Thermodynamics is a curricular unit that confers basic knowledge related to energy, common types of energy and energy transfer mechanisms. In addition to the study of energy variations, it is also relevant to study the consequences of these energy changes on the remaining properties of the system, and their physical characteristics. In Industrial Engineering course, which requires basic knowledge of energy transfers, energy sustainability in industrial systems, energetic balances and imbalances on different systems, energy calculations in heat engines, heat pumps and refrigerators, it is easily understood that thermodynamic is one of the most important and transverse disciplines with direct or indirect applicationin on several other curricular units of this course

Objectives
Objectives
The student is expected to acquire understanding of the basic concepts of thermodynamics as the notion of thermodynamic state, equilibrium state, thermodynamic properties, pure substances, equation of state and thermodynamic process. Should also be able to Apply the first law of thermodynamics to simple closed and open systems, which includes the calculation of work and heat transferred in several processes, and apply the second law of thermodynamics with Calculation of entropy variations in reversible and irreversible thermodynamic processes. In general, the student is expected to acquire technical skills and both the ability to develop a structured reasoning in the formulation and solution of heat transfer problems and to apply theoretical and pratical notions to different effects in everyday life.

Teaching methodologies
Teaching methodologies
During theoretical classes, in addition to the fundamental concepts and relationships discussed in each chapter, some "Case Questions" are analyzed using real systems and focusing the attention on solving problemas methodologies and using practical issues related to the concepts or relationships discussed. In the lectures that end each chapter or sub-chapter, students are challenged to answer a conceptual quiz, focused on the understanding of the basic concepts. Regarding the practical application and mastery of the problem-solving process, students are challenged to solve in class a known set of proposed exercises and those not solved in class due to different execution speeds of the students, can be solved outside classes and submitted for correction. At the beginning of the semester, students will be divided into groups and assigned themes to each group. The work is developed during all semester, integrating the knowledge that is being taught.

Assessment
Assessment
Avaliação Contínua:
Testes (T) - 3 Testes distribuídos pelo semestre. Todos os alunos com nota igual ou superior a 7 valores farão uma prova oral complementar a cada teste. A nota da componente (T) é dada pela Média ponderada das 3 provas escritas (40%) e das 3 provas orais (60%) e tem ponderação de 80% para a nota final da uc. Caso a nota média dos 3 testes seja inferior a 8,0 valores ou a nota de cada teste seja inferior a 6 valores, os estudantes têm de realizar uma prova global equivalente aos 3 testes ou a recuperação de 1 ou de 2 dos testes.
Trabalho Autónomo (TA) - Contribui para a avaliação contínua o trabalho autónomo desenvolvido pelo aluno, que contempla a resolução/entrega de problemas semanais propostos e/ou a apresentação de trabalhos em grupo sobre temas a definir e/ou a realização de um trabalho prático e/ou a realização de quizzes ou aulas invertidas. Esta componente de trabalho autónomo tem uma ponderação de 20% para a nota final da UC distribuída do seguinte modo: Componente escrita dos trabalhos 5%; Resolução de problemas ou Quizes propostos 2,5% e componente oral dos trabalhos 12,5%.
A nota de Avaliação contínua NAC = 0.8*(T) + 0.2*(TA).
Requisitos para aprovação por avaliação contínua: Nota (NAC) > ou = a 10 valores desde que a média das frequências seja igual ou superior a 8,0 e nenhum dos testes seja inferior a 6 valores.
Exame:
Os alunos não aprovados por avaliação contínua podem fazer um exame final na época de recurso. O Exame de recurso é escrito e sempre complementado com prova oral para os casos de nota da componente escrita igual ou superior a 9 valores. Componente escrita vale 40% e a componente oral vale 60%. Requisitos para aprovação por exame (NEx): Nota > ou = a 10 valores.Descrição
