All substance is made up of molecules, the smallest portion of a substance containing all the elements of that substance. Water is composed of two parts hydrogen and one part oxygen. The smallest part of water containing two parts hydrogen and one part oxygen is a molecule. All molecules are strangely in motion, except at the temperature of -460 F. At this temperature molecules are said to be at rest. At this temperature, no heat exists. As the temperature rises above this point of absolute zero, the molecular activity increases and a substance can be said to contain heat. Heat then may be defined as a form of energy due to the molecular motions of a body. If the molecular motion of a body is increased, the body becomes hotter. If a piece of metal is struck with a hammer, both the metal and the hammer become heated, because of the blow. The principal sources of heat are (1) the sun and stars; (2) the interior of the earth; (3) chemical action, such as the combustion of wood, coal, gas, or oil; (4) electrical energy, as in the filament of an incandescent lamp; and (5) nuclear energy.
Download Tips
No doubt, information is the highway to greatness in life. In a bide to obtain such information one is forced to get it whenever it appears online. One is please and satisfy with the rate of such information transfer if it is very fast. But the reverse is case when the data transfer ( i.e. bits or bytes per second ) is very slow. One is bound to waste time to be used for other demanding issues on a slow data transfer. But you can get out of this mess and speed up the rate of data transfer of your computer by applying the tips in this article.
Change or upgrade your connection. Your internet service provider render service according to your subscription. There is a limit speed associated with each connection. So, go for subscription that meet up with your need. If you are using dial-up connection, make use of Broadband connection for faster speed output. The broadband has Direct Service Line ( DSL) or a cable connection to be chosen for maximum performance.
