Science question.anybody know?

Using either one of the following methods, how do these objects work when putting out a fire?Removing the fuel - a fuel is anything that will burn.Removing the heat - throwing water onto the fire cools it down.Smothering the fire to cut the supply of air.Carbon dioxide extinguisher - how it is used: pointed and sprayed onto the fire forming an invisible blanket. - how it works: ?Fire blanket - how it is used: a non - flammable blanket is placed over the fire. How it works:?Water - how it is used: water is hosed onto the fire. How it works:?Sand - how it is used: sand is thrown onto the fire. How it works:?Thanks.

seperate systems. they just opperate in a simular way, that is why they both use dot3 or dot4.

same fluid but completely different things

As other people have stated removing one of the three elements that a fire needs to burn will extinguish the fire. You can see how carbon dioxide extinguishers work and should be used on our website: www.firemart .uk/webshop/2kg-carbon-dioxide-co2-fire-extinguisher

Actually, all of those objects work by limiting/excluding oxygen from the fire. Water doesn't cool it down, it replaces the air, and without oxygen the fire smothers. Same with all of those others; they're all heavier than air and won't burn through/be damaged before the fire smothers. This is actually one of the reasons why pouring water on an oil fire doesn't work; the water just falls straight to the bottom, and the fire rises above it before it can be smothered. Water can also help by making additional fuel unsuitable to burn; if you soak down everything around a fire that's too large to smother, you can 'kill' the fire by letting it burn out. This is why firefighters will sometimes hose down surrounding buildings during a fire, to prevent it from spreading. But if you're talking about applying anything to the fire directly, you're looking at excluding oxygen, or *possibly* trying to make the current fuel unsuitable, but that last approach is tricky.

Fire needs 3 things: fuel, oxygen, ignition source. Take one of these away and you can't have fire. The extinguisher, blanket, water, and sand all cut off the oxygen supply.
