A evolução histórica da máquina térmica de Carnot como proposta para o ensino da Segunda Lei da Termodinâmica

Abstract

History and Philosophy of Science (HFC) has gained ground as an instrument to facilitate the teaching / learning for teachers and students of the sciences. This phenomenon can be explained by the degree of difficulty to explain / understand some scientific principles, when exposed out of context. The HFCs, to situate the scientific changes in the historical and philosophical context, at the same time it facilitates understanding, enables interdisciplinary practice in the academic environment. Our work is part of this new trend and the central idea was to create an innovative proposal of teaching from a problem that we see in the physical education field; the difficulty of understanding the Second Law of Thermodynamics. To this aim, starting from the HFC and the context of the Industrial Revolution, we conducted a literature search of exploratory and qualitative character on the subject and situate the importance of Carnot machine and its relation to our problem. As a result, in addition to academic text, we built a paradidactic and a proposal for practical application in the classroom and hope that these instruments contribute to the construction of an innovative teaching proposal.
