However, when oil and water are forced together, water molecules tend to organize themselves into a structured "cage" around the oil droplets. Substances with similar polarity levels are generally soluble in one another.
How Structured Water Cage Traps Oil Droplets
Because the energy cost is too high and the benefit is low, the mixture is thermodynamically unfavorable. This polarity allows water molecules to form strong hydrogen bonds with each other, creating a tightly bound network.
Furthermore, mixing increases the disorder, or entropy, of a system. Polar substances, such as salt or sugar, readily dissolve in water because their charges can interact favorably with the polar water molecules.
How Structured Water Cage Traps Oil Droplets
Without these biological and culinary workarounds, the world as we know it—with functioning circulatory systems and creamy dressings—would be impossible. The energy required to separate water molecules for oil is greater than the energy gained.
