Thermal Physics Fundamentals: Properties of Matter

Why do materials expand when heated, and how does heat actually move through different substances? Understanding the thermal properties of matter is essential for mastering physics and solving real-world engineering challenges. This text-only course guides you through the fundamental concepts of thermal physics, taking you from absolute basics to a confident understanding of heat transfer and thermodynamic behavior. What you'll learn: - Define the core concepts of heat, temperature, and thermal equilibrium. - Calculate thermal expansion in solids, liquids, and gases using standard physical formulas. - Analyze heat capacity, calorimetry, and phase changes with step-by-step written examples. - Explain the three modes of heat transfer: conduction, convection, and radiation. - Apply Newton's law of cooling to predict temperature changes over time. - Explore modern thermal management applications, such as heat dissipation in electronics. You will begin with essential terminology and temperature scales, progress through thermal expansion and calorimetry, and conclude with the laws of heat transfer and cooling. Every module features detailed written explanations, clear formulas, and practice problems to reinforce your learning. This course is designed for introductory physics students and anyone seeking a clear, structured introduction to thermal physics. No prior thermodynamics knowledge is required.
