Factors Affecting Evaporation

1. We are well aware of the fact that evaporation is a surface phenomenon. Therefore increasing the surface area increases the rate of evaporation.

2. Increasing temperature also increases the rate of evaporation because with the rise in temperature number of particles get enough kinetic energy to convert into vapour state.

3. Content of water vapour in the atmosphere is known as humidity.

4. It is a well known fact that air can hold water upto a certain amount.

5. If the amount of water in atmosphere is already high then rate of evaporation will decrease. Therefore decreasing the humidity also increases the rate of evaporation.

6. It is commonly observed that clothes dry at a fast rate during windy days. This is because with the increase in wind speed the ater particles move away with the windwhich in turn decreases the amount of water vapour from the atmosphere.

7. Therefore increasing the wind speed increases the rate of evaporation.
