CICLOS TERMODINÂMICOS + LEIS DA TERMODINÂMICA + CICLO DE CARNOT | Professor Fabrício Pessoa

In this lesson, Professor Fabrício Pessoa covered cyclic transformations, a fundamental topic for more complex and important subjects in the main university entrance exams in Brazil, especially the ENEM. He also addressed the second law of thermodynamics in a very didactic and simplified way. Heat engines are recurring elements in exams, and Professor Fabrício Pessoa covered this in a very complete and in-depth manner. He discussed the difference between an engine and a refrigerator and how to differentiate them on a graph. In other words, he talked about the direction of the cycle and its relationship to the type of heat engine. Finally, the professor covered the Carnot cycle very well, which is also extremely important for university entrance exams throughout Brazil.
