Thermal Physics: Heat Transfer and Phase Changes

This lecture covers the concepts of heat transfer through conduction, convection, and radiation, as well as phase changes such as solidification, fusion, vaporization, and sublimation. It explains the relationship between temperature, energy transfer, and phase transitions, emphasizing the importance of latent heat. The instructor discusses the behavior of fluids when heated, the mechanisms of energy transfer in different materials, and the role of electromagnetic waves in energy transport. The lecture concludes with an overview of the electromagnetic spectrum and its various energy domains, from radio waves to cosmic microwave background.
