Oil molecules, on the other hand, are nonpolar; their electrical charges are evenly distributed. This phenomenon occurs because of fundamental differences in the physical properties of the two liquids, primarily their density and polarity.
Why Oil and Water Do Not Mix: The Science of Separation
This separation is a natural consequence of the system moving toward a state of lower energy, where the incompatible molecules reduce their unfavorable interactions. Instead of breaking apart the hydrogen bonds in water to mix in, the oil molecules cluster together, minimizing their contact with water and maximizing their cohesion with one another.
This reformation of the layer demonstrates that the separation is a stable, equilibrium state driven by the physical properties of the substances, not a temporary reaction. 9 g/mL Polarity Polar Nonpolar Interaction Hydrophilic Hydrophobic Environmental and Industrial Implications.

Pouring a tablespoon of olive oil into a clear glass of water shows the liquid quickly rising to the top and spreading into a thin film. 93 grams per milliliter.
