All solid materials conduct heat, but some do a better job than others. Generally, metals are good conductors while porous materials are not. Styrofoam is an example of a poor conductor. It is a great insulator. Good conductors of electricity are usually

All solid materials conduct heat, but some do a better job than others. Generally, metals are good conductors while porous materials are not. Styrofoam is an example of a poor conductor. It is a great insulator. Good conductors of electricity are usually good conductors of heat.

The easiest way to explain heat transfer by RADIATION is by the heat we feel from the sun. Even though the sun is about 93 million miles away from the earth, we still feel some of its heat. It travels to earth through the vacuum (no air) of space by way of rays!

» Well, that's a quick look at HEAT ENERGY! We'll cover some of the same material in the lessons on Thermodynamics, Temperature, Heat Transfer and the Properties of Materials.
» The resistance is a consequence of the motion of charge through a conductor: in metals, for example, resistance is primarily due to collisions between electrons and ions. Ohm's law is a basic law of circuit theory, stating that the current passing through

» Historical contextIn a 1847 lecture entitled On Matter, Living Force, and Heat, James Prescott Joule characterized the terms latent heat and sensible heat as components of heat each effecting distinct physical phenomena, namely the potential and kinetic e
