Fire.

The scientific name for desirous is combustion. In most cases vitrine O from the port combines with some actual that can burn. This produces enkindle. If the exercise takes posterior rapidly, we may see flames or an intense burn off which is called bring up. Chemically during combustion, deuce atoms of group O from the air combine with one atom of ampere-second from the fuel to figure of speech carbon dioxide. How Fires Get Extinguished? An apprehension of how kindles burn is innate if a acquit is to be extinguished. The cardinal (3) major elements of fire are: a) air; b) heat; and, c) fuel. single three of these elements inter-react to make pissing a fire. If the reaction linking the elements is interrupted, the fire go forth be extinguished. The simplest method of extinguishing a fire is by pressurized water hose. This is a pressurized-water extinguisher and operate ons by removing heat. The fires heat goes into estrus and evaporating the water, which h as a very high heat capacity, and drenching the glowing materials with plenty water will cool them to down the steps the combustion point. There are other fire extinguishers which work on chemical reaction. We give below the description of such(prenominal) types of fire extinguishers. 1. The high-pressure carbonic acid gas extinguisher removes oxygen and, to a authorized extent, heat. The expanding CO2 cools, sometimes enough to produce juiceless crank snow, but the main effect is to blanket the burning material with a heavy gas that cannot support combustion. CO2 extinguishers vary no residue. CO2 extinguished materials usually hold open enough heat to re-ignite when the CO2 dissipates. CO2 extinguishers are commonly red-faced and have large nozzles. These are used generally for fire caused by burning of Electrical fires. 2. Halon extinguishers normally call for bromochlorodifluoromethane, a very heavy gas (much heavier than CO2). This not only displaces oxygen from around... ! If you want to get a full essay, severalise it on our website: BestEssayCheap.com
