WebHeat can be transferred by conduction only in solids. If one end of a solid is heated, the particles of the solid gain kinetic energy. This means that they move faster. In a solid the particles are held together by strong forces of attraction. The only way in which the particles can move is to vibrate forwards and backwards. http://www.ingridscience.ca/node/470
