Question

Name three factors which affect evaporation.

Answer 1

Evaporation is a process in which a liquid changes into vapours even below its boiling point. Factors that affect evaporation are:

1. Temperature
2. Surface area
3. Humidity
4. Wind speed
5. Nature of the liquid

Three factors that affect evaporation are explained below:

• Temperature: The greater the temperature of the liquid and its surroundings, the faster the rate of evaporation.
• Surface area: Since evaporation is a surface phenomenon, the greater the surface area occupied by the liquid, more the rate of evaporation.
• Humidity: The greater the humidity of the atmosphere surrounding the water, the slower will be the rate of evaporation.
