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 …
Converting water into steam absorbs a huge amount of thermal energy (heat), so that helps to prevent heat transfer that will start combustion in more of the fuel. The steam also blocks, or reduces, the flow of oxygen into the fuel. Without oxygen, the fire will extinguish.

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?
