con·duc·tion
(kən-dŭk′shən) The flow of energy, such as heat or an electric charge, through a substance. In heat conduction, the energy flows by direct contact of the substance's molecules with each other. Although the molecules vibrate, they do not change position in the transfer of energy. In electrical conduction, energy flows by the movement of electrons or ions.
Did You Know? Heat is a form of energy that results in the motion of molecules. Heat travels by conduction, convection, or radiation. In conduction, heat spreads through a solid by making its molecules vibrate faster. As faster molecules bump slower ones, the slower ones are made to vibrate faster, and the solid becomes hotter. This is how the handle of a teaspoon sticking out of a cup of hot tea eventually gets hot. When liquids and gases are heated, their molecules, which are free to move about, move farther apart. The hotter portions of the liquid or gas expand, become less dense, and rise, and cooler portions move down to take their place. This movement causes the liquid or gas to circulate in the process called convection. The currents of the ocean are convection currents caused by the uneven heating of the ocean waters by the sun. Radiation carries heat in the form of waves through space. A hot object, like the hot wire in a heat lamp, gives off energy waves called infrared rays. When these rays strike an object, its molecules absorb the rays' energy and vibrate or move faster, and so the object becomes hotter. The sunlight that warms your face has traveled through 93 million miles of space by radiation.
