What does it mean for a substance to heat up? What does the temperature of a substance represent? How is heat transferred? In last week's video, we discussed the pre-modern thermodynamic understanding of heat and temperature and the development of the laws of thermodynamics. In this follow-up video, we will examine the difference between the concepts of heat and temperature and the ways in which heat exchange takes place, and then we will see the doors of the quantum world. How do the three different ways of heat transfer, conduction, convection and radiation work? Why are metals a better conductor? How does a heat source in a single point of the room heat the whole room? What is the relationship between heat and light? How did Balfour Stewart explain how the absorption and emission of light relates to temperature? What was Gustav Kirchhoff talking about in the blackbody conjecture? Where was Wilhelm Wien, who formulated blackbody radiation, wrong? How did Lord Rayleigh and James Jeans cause ultraviolet catastrophe with their published work to explain blackbody radiation? How did Max Planck's "quanta" solve this problem and give rise to quantum mechanics? The answer to all these questions is in the video.
