At first glance, the inability of oil and water to mix seems like a simple observation, yet it points to a fundamental principle governing the microscopic world. Energy and Entropy at Play Beyond polarity, the separation is driven by thermodynamics, specifically the concepts of enthalpy and entropy.

Furthermore, mixing increases the disorder, or entropy, of a system. Non-polar substances, including oils, fats, and waxes, lack these charges and therefore cannot form the necessary interactions with water to break apart and integrate.
The energy required to separate water molecules for oil is greater than the energy gained. In stark contrast, oil is typically non-polar, consisting of hydrocarbon chains where electrons are shared more evenly, resulting in a molecule without significant charge differences.

Non-polar molecules (like oil) have an even distribution of electrical charge. This polarity allows water molecules to form strong hydrogen bonds with each other, creating a tightly bound network.
