The Difference Between Evaporation and Degradation While the light fractions of oil do evaporate, the bulk of what we observe as "used oil" does not disappear in the same way a puddle of water does. Understanding this distinction clarifies why a bottle of old motor oil left open loses little mass over time, while a volatile solvent disappears overnight.
Long Term Stability of Oil: Understanding Evaporation Over Time
Understanding the Science of Evaporation To answer the core question, one must first define the scientific process. Evaporation occurs when molecules at the surface of a liquid gain enough kinetic energy to break free from the liquid's intermolecular bonds and enter the atmosphere as vapor.
This residue can persist in the ecosystem for years. Heavy residues: These molecules are too large to escape easily and remain liquid.
Understanding Long Term Stability and Evaporation Rates
This process is specific to the molecular weight and structure of the liquid; lighter molecules with weaker bonds, such as water or alcohol, evaporate quickly, while heavier, complex molecules exhibit lower volatility. The short answer requires a distinction between true evaporation and the broader category of liquid degradation, as the volatility of different hydrocarbon chains dictates the fate of the substance.
