Answer» Combustion, orburning,is a high-temperatureexothermicredoxchemical reactionbetween afuel(the reductant) and anoxidant, usually atmosphericoxygen, that produces oxidized, often gaseous products, in a mixture termed assmoke. Combustion in afireproduces aflame, and theheatproduced can make combustion self-sustaining. Combustion is often a complicated sequence ofelementaryradical reactions.Solid fuels, such aswoodandcoal, first undergoendothermicpyrolysisto produce gaseous fuels whose combustion then supplies the heat required to produce more of them. Combustion is often hot enough thatincandescentlightin the form of eitherglowingor aflameis produced. |
