Summary
Chapter 14 on Heat explores how microscopic kinetic and potential energies constitute a system’s internal energy, and how energy is transferred as heat or work. The chapter elaborates on specific heat, latent heat, calorimetry, and phase transitions, underlining that temperature change due to heat flow depends on both the amount and type of substance. It also explains heat transfer mechanisms – conduction, convection, and radiation – along with important laws such as Fourier’s law. An understanding of these principles is essential for solving real-world problems in thermodynamics, engineering, and everyday phenomena such as insulation and cooking.
