Conduction of Heat in Solids H. S. Carslaw, J. C. Jaeger

Heat can be transferred from one place to another by three methods: conduction in solids, convection of fluids (liquids or gases), and radiation through anything that will allow radiation to pass. We'll also introduce radiation, gravity and heat conduction in solids. Transfer of heat in solids is by conduction. It is also a term that describes processes affecting the atmosphere, waters, and solid earth. There is a simple solution, but first let's learn a little about heat conduction: 1. Such bad conductors of heat are called insulators. Let's talk about heat – solids, liquids, and gases are made up of molecules. Convection is the name for a means of heat transfer, as distinguished from conduction and radiation. Transfer of heat within a fluid is by convection. Liquids: Most of the liquids transfer heat very well. Any radiation which is absorbed turns into heat. Conduction usually can occur in solids such as various types of metal and glass. These waves have different wave lengths depending on the temperature of the heat source. Conduction heat transfer is the heat transfer through medium without accompanied by displacement of the particle medium.
