This Thermodynamics Course discusses the basic concepts (macroscopic and microscopic) of thermodynamics, thermal balance, 0th law of thermodynamics, equation of state, thermodynamic processes (quasi-static, reversible and irreversible, and cyclical), 1st law of thermodynamics equation. , The relationship between internal energy, heat and work in ideal gas systems, isolated systems, closed systems and open systems, as well as their applications in everyday life. Isothermal, isochoric, isobaric and adiabatic processes. Carnot cycle in an ideal gas system, Entropy of a thermodynamic system, Enthalpy, Gibbs function, and Helmholtz function, Equation of the 2nd Law of Thermodynamics, and its application in everyday life, in the form of case studies, such as: (1) The working principle of a steamboat engine , (2) the release of a certain gas in the reaction between the vinegar solution and baking powder so that it can inflate the balloon, (3) the working principle of a rice cooker, and (4) the working principle of a refrigerator and air conditioner. Accompanied by 2 practical activities from the following 4 selected topics: (1) Adiabatic gas law, (2) Ideal gas, (3) Thermal Expansion, and (4) Heat engine.
