Why do perfumes smell stronger when warmed?
ChemistrySenses
Quick Answer
Heat increases the rate at which perfume molecules evaporate into the air. More airborne molecules means a stronger smell reaches your nose.
The Full Story
Smell depends on volatile molecules entering the air and traveling to your nose. When a perfume is warmed by skin or the environment, its molecules gain more kinetic energy and evaporate faster. That increased evaporation raises the concentration of scent molecules in the air, making the fragrance seem stronger. This is one reason perfumes are designed to interact with body temperature.
Key Facts
1.Warming increases evaporation rate
2.Smell depends on volatile molecules reaching the nose
3.Perfume is often applied to pulse points for this reason
