Fundamentals of Thermodynamics: Heat, Work, and Energy

Have you ever wondered why some materials feel colder than others, or how an engine converts heat into motion? Understanding the physics of thermal energy unlocks the secrets behind countless processes in the world around us. This course provides a comprehensive introduction to classical thermodynamics and heat transfer. You will move beyond simple definitions to grasp the rigorous mathematical and conceptual frameworks that define how energy flows, transforms, and is utilized in engineering and natural systems. What you'll learn: * Understand the core concepts of temperature, heat, internal energy, and the foundational Zeroth Law of Thermodynamics. * Apply the First and Second Laws of Thermodynamics to analyze energy conservation, work cycles, and the concept of entropy in closed and open systems. * Master the three primary modes of heat transfer—conduction, convection, and radiation—and calculate heat flow through various materials. * Practice calculating the maximum theoretical efficiency for common thermal machines, such as engines and refrigerators, using ideal cycles. * Analyze phase changes and material properties (like specific heat capacity) essential for modern thermal management applications. The course begins with foundational terminology and the laws of thermodynamics, progressing systematically through the mechanisms of heat transfer and practical applications in energy conversion and material behavior. This course is designed for absolute beginners with no prior experience in physics or engineering, requiring only basic mathematical literacy.
