Any radiation which is absorbed turns into heat. We'll also introduce radiation, gravity and heat conduction in solids. It is also an efficient method of conduction in liquids, but occurs hardly at all in gases. Conduction is the mechanism by which heat is transferred within material objects and between material objects that are in physical contact with one another. This is the primary method of heat transfer in solids and it works best of all in metals (because loosely bound electrons play a role). When one end of an object is supplied with thermal energy, the molecules gain kinetic energy and vibrate vigorously. Conduction; that is, heat being transferred from a heated solid to an unheated solid. As they vibrate faster, they will collide with neighbouring particles making them vibrate too. These waves have different wave lengths depending on the temperature of the heat source. Convection; that is, the transfer of heat from one place to another through the movement of fluids or gases.
