Document Summary
Franklin observed that science isn"t necessarily the mother of technology. Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1] slower oxidative processes like rusting or digestion are not included by this definition . The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. [3] depending on the substances alight, and any impurities outside, the color of the flame and the fire"s intensity will be different. ] Of the chemical processes now regarded as redox reactions, combustion was the earliest focus of philosophical and scientific attention. The greek scientific philosopher empedocles listed fire as one of the four elements of matter. In more modern times the phlogiston theory enjoyed scientific popularity. This theory was first articulated in 1697 by german chemist g. e.
