EVAPORATION OF WATER

1. Evaporation of water is a process at which water change into water vapour at any temperature below its boiling point.

2. Factors that affect the rate of evaporation :
- humidity
- surrounding temperature
- exposed surface area
- movement of air

3. Humidity lower, rate of evaporation higher

4. Surrounding temperature higher, rate of evaporation higher

5. Exposed surface area larger, rate of evaporation higher

6. Movement of air exist, rate of evaporation higher.
