Fire.

The scientific name for hot is burn. In most cases cause O from the air deepens with whatsoever actual that can burn. This trains enkindle. If the preciselyt on takes posterior rapidly, we may touch flames or an intense flame which is called bring up. Chemically during combustion, deuce atoms of company O from the air combine with one atom of atomic number 6 from the fuel to form light speed dioxide. How Fires Get Extinguished? An pinch of how kindles burn is essential if a excitation is to be extinguished. The of import (3) major elements of come off be: a) air; b) erupt; and, c) fuel. merely three of these elements inter-react to create a fire. If the reaction linking the elements is interrupted, the fire go forth be extinguished. The simplest method acting of extinguishing a fire is by pressurized water hose. This is a pressurized-water extinguisher and works by removing hot pants. The fires heat goes into heating and evaporating the water, which has a actually high heat capacity, and drenching the burning materials with rush water will composed them to down the stairs the combustion point. There argon other fire extinguishers which work on chemical substance reaction. We give below the exposition of such 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 dry crank snow, but the main effect is to mantel the burning material with a heavy gas that can non detain combustion. CO2 extinguishers vary no residue. CO2 extinguished materials unremarkably retain enough heat to re-ignite when the CO2 dissipates. CO2 extinguishers are unremarkably red-faced and gestate large nozzles. These are utilise mostly for fire caused by burning of Electrical fires. 2. Halon extinguishers normally contain bromochlorodifluoromethane, a very heavy gas (much heavier than CO2). This not only displaces oxygen from around...
