章節(jié)摘錄

  Heat and Temperature  The laws of thermodynamics can help us to understand what heat is all about. One ofthese laws states that energy can neither be created nor destroyed, but can he converted fromone form to another. This means that most of the heat the world experiences is not being con-tinuously created but is being converted from other forms of energy like fossil fuels (gas andoil). This heat can also be accounted for when it is transferred from one substance to another.  The term used to describe the quantity of heat or heatcontent is known as the British thermal unit (Btu). Thisterm explains how much heat is contained in a substance.The Btu is defined as the amount of heat required to raisethe temperature of 1 lb of water 1 F. For example, When 1lb of water is heated from 68~F to 69~F, 1 Btu of heat energyis absorbed into the water.  In the metric or SI system of measurement, the termjoule (J) is used to express the quantity of heat. Because aioule is very small, metric units of heat in this industry areusually expressed in kilojoules (kJ) or 1 000 joules. One Btuequals 1. 055 kJ.  Temperature can be thought of as a description of the level of heat. Temperature also is referred to as heat intensity. Both heat level and heat intensity should never be confused with theamount of heat, or heat content. Heat can he thought of as energy in the form of molecules inmotion. The starting point of temperature is, therefore, the starting point of molecular mo-tion.
