Foundational Principles of Thermodynamics

Thermodynamics is the study of energy and its transformations, forming the bedrock for understanding virtually all physical, chemical, and engineering disciplines. This course provides a robust, conceptual foundation built on rigorous definitions and systematic exploration of the core laws. By the end of this course, you will possess a clear, working knowledge of thermodynamic principles, enabling you to analyze energy transfer, predict process feasibility, and calculate efficiency in various contexts. What you'll learn: Understand the definitions of system, surroundings, state variables, and the primary thermodynamic processes (isobaric, isothermal, adiabatic). Master the First Law of Thermodynamics, calculating internal energy, work, and heat transfer in closed and open systems. Apply the Second Law and the concept of Entropy to determine the spontaneity and directionality of physical and chemical changes. Learn how Gibbs free energy and enthalpy relate to equilibrium and reaction feasibility. Practice fundamental calculations involving heat capacity, phase transitions, and ideal gas behavior. Grasp the microscopic interpretation of thermodynamic laws, linking macroscopic properties to molecular motion and statistical principles. We begin with fundamental terminology and the Zeroth Law, progressing systematically through the First, Second, and Third Laws. The course integrates theoretical explanations with practical, written problem-solving exercises. This course is designed for absolute beginners, students, and professionals needing a strong, academic introduction to thermodynamics. No prior knowledge of advanced physics or calculus is required.
