Why cannot gasoline be put out with water?
Why are ignited objects put out with water? The point is that combustion is the process of combining a substance with oxygen, so the main purpose of extinguishing fires is to limit the flow of air oxygen to the burning material.
Extinguishing with water is the cutting off of oxygen to the burning object, since water, by wetting it, envelopes it (besides, water lowers its temperature). Gasoline isn’t mixed with water, and at the same time, is lighter than water, so it just floats up, while keep burning.
In addition, it will begin to spread with the water, increasing the fire area.
