Detailed explanation-1: -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. According to the Scientific American, the reason oils do not mix with water is related to their properties. Water molecules are polar, and oils are nonpolar.
Detailed explanation-2: -Water will sink to the bottom of oil pan due to density difference. Sinking water will vaporize instantly into steam and expand rapidly in volume. Then, oil is explosively expelled in all directions. If there is a fire source, the small oil droplets are then ignited to give a big fire.
Detailed explanation-3: -Once they get up to 100 degrees C, the water will start to boil. And around 257 degrees C, you’ll see the oil start to smoke. But you’ll have to get all the way to 300 degrees C before the oil will boil. So the water boils first and the oil last.
Detailed explanation-4: -Why? For both the hot plate and the microwave, olive oil will heat up faster than water because the heat capacity of oil is lower than the heat capacity of water. Water requires more energy per gram of liquid to change its temperature.
