Explanation:
Detailed explanation-1: -Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water s hydrogen bonds. Water will not do this so the oil is forced to stay separate from the water.
Detailed explanation-2: -Oil is a non-polar molecule, while water is a polar molecule. While all molecules are attracted to each other, some attractions are stronger than others.
Detailed explanation-3: -Oil is nonpolar, meaning its charge is evenly balanced. Because of this, water molecules will only attract other water molecules, and vice-versa. Emulsifiers have a special molecular structure that bind them to both water and oil molecules.
