The science behind something you encounter, use, or wonder about.
The useful idea
- The useful idea
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
- How it works
A high concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water.
- Why it matters
When the molecules of the liquid collide, they transfer energy to each other based on how they collide.
Why this matters
Look for Evaporation the next time you notice this pattern in everyday life.
