To extinguish a fire, you need to do one of three things: Choke off the supply of oxygen. Remove the supply of fuel. Cool the environment & the fuel down enough. If it is a coal fire, and you pour water over it, the water covers the coals, cooling them, and choking off the supply of oxogen
3. Water does not, in general, help extinguish a fire. Typical fires, however, can be successfully attacked using water alone, as it can cool the fuel at the base of the fire or generate a vapor barrier between atmospheric oxygen and the hot fuel. Water can accelerate liquid hydrocarbon fires by dispersing fuel.
Why And How Does Water Put Out Fire? Explained
The water molecule doesn’t become hot enough to separate into hydrogen and oxygen and instead, has two potential actions on the fire that can put it out. Firstly, it absorbs the heat from the fire. This is the main method by which water extinguishes fire. Room temperature water is about 77 degrees Fahrenheit and water won’t become steam until it hits 212 degrees …
Fire extinguishing involves absorption of heat and the absorption of heat in converting hot water to steam is very much more than the heat absorbed in heating cold water to the boiling temperature. Hot water readily converts to steam absorbing enormous amounts of heat and therefore hot water is better for fire extinguishing purposes than cold water. It is true that cold …

What is the least likely chemical to extinguish a fire?
Humble dihydrogen monoxide or H 2 O. This, at first glance, seems to be the least likely chemical on earth to extinguish fires with. After all – it’s made up of hydrogen and oxygen both of which are highly flammable. Why doesn’t it just break down into its constituent elements and make a fire worse, rather than extinguishing it?
Does water kill the fire?
So, no, water doesn’t kill the fire, because in the way that we consider things to be “alive”, fire is not really alive. Are There Circumstances Under Which Water Won’t Put Out Fires? Yes, and, in fact, there are circumstances under which you definitely shouldn’t use water to put out a fire.
