Thermodynamics Fundamentals: Temperature, Heat, and the First Law

Have you ever wondered how energy transforms from one form to another, or how heating a substance changes its physical properties? Understanding thermodynamics is essential for anyone pursuing engineering, physics, or chemistry, yet the core concepts can often feel overwhelming. This text-based course breaks down the fundamental laws of thermal science into clear, logical, and digestible written lessons. You will transition from understanding basic temperature scales to analyzing complex energy transfers with confidence. What you'll learn: - Understand the foundational concepts of temperature, thermal equilibrium, and temperature scales - Calculate thermal expansion in solids and liquids under varying conditions - Analyze heat absorption, specific heat capacity, and latent heat during phase changes - Apply the First Law of Thermodynamics to closed and open systems - Evaluate the three primary mechanisms of heat transfer: conduction, convection, and radiation - Practice solving thermodynamic equations using systematic, written step-by-step methods This course begins with essential terminology, defining temperature, heat, and system boundaries before progressing to thermal expansion and heat absorption. You will then explore the First Law of Thermodynamics and study how thermal energy moves through different environments. Designed specifically for beginners, this course requires no prior background in thermodynamics, though basic algebra is helpful. Start reading today to build a strong, permanent foundation in thermal physics.
