Thermodynamics Fundamentals for Beginners

Thermodynamics is the foundational science behind how energy moves and transforms in our world, yet its mathematical formulas and abstract concepts can often feel overwhelming to beginners. This text-based course breaks down these complex ideas into intuitive, digestible written lessons. You will transition from having zero prior knowledge to confidently analyzing energy systems and understanding how physical laws govern everyday engineering processes. What you'll learn: Understand the foundational definitions of systems, boundaries, surroundings, and state variables; Master the Zeroth, First, and Second Laws of Thermodynamics and their physical implications; Calculate heat transfer, work done, and changes in internal energy for closed and open systems; Analyze properties of pure substances using property tables and state diagrams; Apply thermodynamic principles to basic power cycles and refrigeration processes. The course begins with essential terminology and fundamental concepts of temperature and pressure, before guiding you through the governing laws of energy conservation and entropy, complete with practical written exercises to test your understanding. This course is designed specifically for beginners, engineering students, and curious learners with no prior background in thermodynamics.
