Why does water extinguish fires? As the saying goes: Fire and water are incompatible. Water is the nemesis of fire. When a fire breaks out, firefighters always shoot high-pressure water jets into the flames with water guns. In case of a fire at home, the easiest way is to put out the fire with water in a basin.
Water can extinguish fires because water is the product of hydrogen burning in oxygen and will not burn again. Water is roasted by the flame and turns into water vapor, absorbing a large amount of heat and quickly lowering the flame temperature. At the same time, water vapor surrounds the fire source, isolating oxygen in the air and extinguishing the fire.
However, when oil burns, water cannot be poured because oil is lighter than water. After splashing water, the oil not only continues to burn on the water surface, but also spreads through the water, making the fire stronger. Therefore, to extinguish a fire caused by the burning of oil, a fire extinguisher is needed. If you don't have a fire extinguisher around you, cover it with sand.
