Document Summary
Conduction: the transmission of heat. collisions throughout the metal. conduct heat (and electricity) well. Silver is the best conductor, followed by cooper and gold, and, among the. Solids composed of atoms that have one or more (cid:498) loose(cid:499) outer electrons. Metals have the (cid:498)loosest(cid:499) outer electrons, which arte free to carry energy by. Air is a very poor conduction, which, as we said, is why your hand isn"t harmed. Poor conductors that impede the transfer of heat are called insulators. Figure 16. 1: when you touch a nail stuck in ice, does cold flow from the nail to. Heat is transmitted from a higher to a lower temperature. Such a wall has (cid:498)thermal inertia. (cid:499: unlike conduction, convection involves the motion of (cid:498)blobs(cid:499) of matter- the overall movement of molecules of a fluid. convection: heat transfer due to the actual motion of the fluid itself. Convection can occur in all fluids, whether liquids or gases.
