Heat and Temperature

Introduction

The topic under study relates to several topics related to heat and temperature. It addresses the study of heat relative to the kinetic theory of matter. The topic also revolves around the description about heat, temperature, relation between heat and temperature, their difference, various properties of a substance that determine the heat capacity and different sources of heat. Discussion

Heat

The energy that has the tendency to get transfer from one body to another because of the thermal contact or radiation is known as heat. The body to which energy transfers possess different temperature. As a process, the description of heat relates to the process in which energy transfer takes place between physical bodies. The transfer takes place because of any thermodynamic process. The earliest uses of geothermal energy involved hot water associated with natural hot springs and geysers. Since 1913, however, with the construction of the world's first commercial geothermal power generator in Larderello, Italy, experts have explored ways to obtain inexpensive electricity from the Earth's heat—with considerable success. Although called a “renewable energy source,” the scale of most power plants means that they “mine” the heat; that is, extract it from the localized area far faster than any natural recharge (Wallace & Hobbs, 2006). Overall, however, the resource base is so immense that no one believes that man will exhaust it in the foreseeable future. Production from different fields, however, may decline because the fluid is being extracted faster than the natural recharge (demonstrated by changes in gravity).

Temperature

Temperature refers to as the property of any matter, which is physical in nature and, expresses the degree of coldness or hotness in quantifiable form. Objects those possess low temperatures, are said to have a degree of coldness whereas, objects with high temperatures possess a degree of hotness. Temperatures decrease with altitude in the mesosphere, similar to the troposphere, and the lowest temperatures in the atmosphere occur in this layer (as low as -130 °F, on average). At the top, of the mesosphere lies the mesopause, a region of stable temperatures with height. Above the mesopause, at 50 mi. In altitude, the final thermal layer of the atmosphere exists, which is called, the thermosphere (Rubin & Davidson, 2001). Here, the small fraction of atmospheric gas that remains exists between Earth and space, and in fact, the exact boundary between the atmosphere and what we consider ...
