Evaporation is the vaporization of a liquid below its boiling point, where no boiling occurs. The rate of evaporation depends on four main factors: the temperature, the surface area of the liquid, the humidity of the surrounding air, and wind speed, with higher temperatures, greater surface areas, lower humidity, and higher winds all serving to increase the rate of evaporation.

3. Evaporation
• Theoretically, evaporation means simply
vaporization from the surface of a liquid.
• Vaporization of a liquid below its boiling point
is called evaporation.
• No boiling occurs and the rate of vaporization
depends on the diffusion of vapour through
the boundary layers above the liquid.

4. Factor Affecting Evaporation
• There are 4 factors to affect evaporation.
1) Temperature
2) Surface area
3) Humidity
4)Wind Speed
