Book excerpt: Excerpt from A Text-Book of Inorganic Chemistry, Descriptive, Theoretical, and Practical, Vol. 1: A Manual for Advanced Students; Non-Metallic Elements T hey may change position, color, structure, temperature, and, in fact, may undergo almost innumerable other changes. If a polished piece of iron is exposed to the air, its bright surface becomes covered with a reddish-colored matter if a current of electricity is passed through it, it attracts other pieces of iron; if it is exposed to a high temperature, it becomes red. Energy in some of its many forms causes these changes. Energy is sometimes defined as the power to do work, as the power to overcome resistance z'.e. To change the position or relation of bodies or parts of bodies. Work is the act of producing a change in opposition to force. Forms of Energy. There are many forms of energy, such as heat, light, chemism, motion, and electricity. Each of these forms of energy may be accompanied by, and may be changed into, other forms. Examine, for example, the pro duction of electrical energy, taking as the starting-point the burning of the fuel under the boiler. The chemical energy pro duced by the burning of the fuel is transformed into heat and light energy by the water this energy is changed to molecular energy or energy of motion; this sets in motion the engine, which in turn starts the dynamo, which in its turn converts this motion into electrical energy. The electrical energy meets with resistance at the lamps and is converted into heat and light again. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
