First Steps in Thermodynamics

Ever wondered how engines work, why some reactions happen spontaneously, or how refrigerators cool? Thermodynamics provides the fundamental answers to these and countless other questions about energy and its transformations. This course offers a clear, text-based introduction to the core principles of thermodynamics, empowering you to understand and analyze energy interactions in physical and chemical systems. What you'll learn: Understand foundational thermodynamic concepts like systems, states, processes, and properties. Learn the First Law of Thermodynamics and apply it to energy conservation and internal energy changes. Apply the Second Law of Thermodynamics to analyze entropy, spontaneity, and the direction of processes. Explore the Third Law of Thermodynamics and its implications for absolute zero and residual entropy. Practice calculating heat, work, enthalpy, and Gibbs free energy for various thermodynamic processes. Analyze the efficiency of common thermodynamic cycles, such as those found in power generation and refrigeration. Connect thermodynamic principles to modern applications in energy efficiency and environmental sustainability. The course starts with essential terminology and basic definitions, then systematically introduces each of the three laws of thermodynamics, followed by practical applications and problem-solving techniques. This course is specifically designed for beginners with no prior background in thermodynamics, making it ideal for students in science or engineering, or anyone interested in the science of energy. Begin your exploration of the fundamental laws governing energy and its behavior.
