Detailed explanation-1: -What happens if you add water to a grease fire? Even a small amount of water dropped into a pan or deep fryer filled with burning oil will sink to the bottom, become superheated and erupt.
Detailed explanation-2: -Oil is less dense than water so when water is thrown in a burning pan full of grease, it immediately goes under the grease to the extremely hot surface of the pan. This turns the water to steam instantly, not before rapidly expanding to 1700 times its original size. “That very quickly pushes all the oil out of the pan.
Detailed explanation-3: -Water is heavier than oil. On spraying water, it sinks and oil floats, and the fire continues. Water is lighter than oil and it floats on the surface of the oil.
