Lecture
This lecture introduces thermodynamic cycles, focusing on efficiency and the Otto cycle. It covers topics such as heat engines, maximum efficiency, gasoline engine (Otto cycle), and the concept of thermal machines. The instructor explains the relation between different thermodynamic variables within an equilibrium system, the ideal gas equation, and the thermodynamic identity for quasi-static transformations. Additionally, the lecture delves into the efficiency of engines, the limitations of the Otto cycle, and the working principles of gasoline and diesel engines.
