Cooling action results to some extent from absorption of heat by water particles but mostly from the conversion of water to steam. When converted into steam, 1lb of water at 60OF absorbs 1150 Btu. When the surface of the burning material is cooled to a point where flammable vapors are no longer evolved, the fire is extinguished.
