Chemical Changeand Combustion Process - Essay Example

Within liquid, it is normally rare for oxygen gas to penetrate thus the surface layer is commonly oxidized. Solid fuel fire such as wood contains volatile oils that normally evaporate and burn into corresponding flames. Carbon is normally left after solid combustion and then sublimates from the underlying surfaces of the hot substance thus combusting as a gas.

            Oxidation is a chemical change that mainly produces heat energy during the combustion process. It mainly creates sufficient heat that starts fire via the creation of required oxygen that subsequently causes combustion (Horsfall, 2002). Oxidation can either add oxygen or remove hydrogen

            Combustion can be stopped by the removal of the heat by cooling the underlying burning material, cutting the supply of either fuel or air source, and adding chemical substances. Cooling of the material is normally done by water, which acts blanket and evaporates in contact with fire thus cutting off the supply of oxygen for combustion thus halting it. Smothering agents are commonly utilized in cutting the underlying supply of oxygen such as carbon dioxide and they ought to be utilized on energized electrical equipment as the electrical conductor normally conductor electricity (Horsfall, 2002). Combustion is halted by removing the fuel supply by switching off electrical power and solid fuel. All three processes are mainly treated by carbon dioxide as the main chemical.
