Explanation:
Detailed explanation-1: -Water and oil do not mix. They are said to be immiscible. This is because water is a polar molecule – its structure means that is has a positive charge one end and a negative charge the other end.
Detailed explanation-2: -The first thing you will observe is that oil and water will not stay mixed together, no matter how hard you shake the jar. Instead, the oil slowly rises to the top of the water. This is because of the density of the two liquids. Density is a measure of the mass per unit volume of a substance.
Detailed explanation-3: -However if oil and water are shaken together, droplets of one liquid will mix into the other. This mixture is called an emulsion.
