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.
How Temperature Changes the Rate Oil Evaporates
When motor oil sits in a pan, it appears to persist, but this is largely due to the oxidation and polymerization occurring within the liquid. 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.
Environmental and Practical Implications In an environmental context, spilled oil on water presents a unique hazard precisely because the volatile fractions evaporate quickly, leaving behind a heavier, more toxic sludge. Understanding the Science of Evaporation To answer the core question, one must first define the scientific process.
How Temperature Dramatically Changes Oil Evaporation Rates
Light distillates: These molecules evaporate fast due to low molecular weight. Medium fractions: These contribute to odors and moderate evaporation rates.
