Bitesize conduction
WebA conductor is a material that allows internal (thermal) energy to be transmitted through it easily. All metals are good conductors. When one end of a metal rod is put into a fire, the energy from... WebI am studying heat transfer and have learned there are three kinds of heat transfer: conduction, convection, and radiation. Some examples are: Conduction: Touching a stove and being burned; Ice cooling down your hand; Boiling water by thrusting a red-hot piece of iron into it; Convection: Hot air rising, cooling, and falling (convection currents)
