nductor of heatand that glass is a poor conductor of heat. When heat moves fromone part of a substance to another without visible motion of the partsof the substance, the method of heat movement is known as conduc-tion. The process of conduction is as follows: The moleculesof that part of the body… … FIG. 74. — Conduction in solids. away, and so on. Thus the energy of motion of the molecules,or heat, ntoves from the hot part of the body to the cooler part.We can make a rough comparison of the conducting power ofsolids by the experiment illustratedin Fig. 74. Rods of the solids arecoated with…
