Trabalho de Conclusão de Curso (Bacharelado em Física) - Instituto de Física, Universidade Federal de Goiás, Goiânia, 2023.http://repositorio.bc.ufg.br//handle/ri/23816This monography provides a comprehensive overview of classical and quantum thermodynamics. The classical formulations of thermodynamics are discussed in detail, including concepts such as energy and equilibrium, ideal gases and internal energy. Study the first and second laws of thermodynamics and their applications to mechanical work, heat engines and thermodynamic cycles. The present work also covers some quantum thermodynamics principles, including the use of density operators to describe pure and mixed states of quantum systems and the time evolution of these operators. The first law of quantum thermodynamics is introduced, along with the concepts of quantum adiabatic evolution and quantum Otto cycles. In addition, this monography briefly discusses the concept of Maxwell’s demon in the context of quantum thermodynamics and its implications for the second law. Overall, this work provides a comprehensive introduction to the basic principles of classical and quantum thermodynamics.engAttribution-NonCommercial-NoDerivatives 4.0 InternationalThermodynamicsQuantum heat enginesOtto cycleTermodinâmicaMáquinas térmicas quânticasCiclo de OttoTCC
