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 …
A wood fire usually burns at 300–500 ° C and the minimum ignition temperature is about 180 ° C, so boiling water is still cold enough to put out a fire. Water also has a high enthalpy of vapourisation, which means it requires a lot of energy to make it boil off when it is at its boiling point, so boiling water would still be able to absorb enough energy to make it reasonably …
The Science of Water Extinguishment | Firehouse
Think of how much energy it takes to heat a liter of water to a boiling point every time you put on a kettle. … Extinguishing a room on fire. …
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. Water can generate explosive gaseous mixtures when applied to some …

How does water extinguish 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 Fahrenheit (the boiling point of water).
Can water put out a fire?
However, we just need to stress again that water can’t put out all fires. While ordinary fires of solid material are often easily extinguished with water, electrical fires, oil or liquid fires, and metal fires should never be tackled with water. You are at a high risk of harming yourself, property, and others if you do so.
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?
What do you need to start a combustion reaction?
You need a fuel (that is whatever is going to be burned), you need oxygen or another oxidizer (which allows for the fuel to react in an exothermic manner we call “burning”) and you need heat.
