Rate of Evaporation
- Evaporation is the process of converting a substance (such as water) from its liquid state to its gaseous state at temperature lower than the boiling point of the liquid.
- There are several ways of making a liquid evaporate faster:
- Increase its temperature
- Increase its surface area
- Pass air through it or across its surface
- Make the liquid into a fine spray
A spray is made up of millions of tiny liquid droplets with a very large total surface area. The highly curved surfaces make it easier for molecules to escape.
