What are the factors affecting evaporation? Explain any three factors affecting evaporation?

Temperature, the surface area of the liquid, the humidity of the air, wind speed, atmospheric pressure, and intermolecular attraction are the factors affecting evaporation.

The factors affecting evaporation -

i) Temperature:  The temperature of the liquid plays a significant role in evaporation. Higher temperatures provide more thermal energy to the liquid molecules, enabling them to overcome intermolecular forces and escape into the gas phase more readily. As a result, higher temperatures lead to increased evaporation rates.

ii) Surface Area: The surface area of the liquid exposed to the surrounding environment also influences the rate of evaporation. A larger surface area provides more opportunities for molecules to escape from the liquid phase and enter the gas phase, leading to faster evaporation.

iii) Humidity: The humidity level of the surrounding air affects the rate of evaporation. Lower humidity levels create a larger difference in vapor pressure between the liquid and the air, promoting faster evaporation. On the other hand, high humidity levels, where the air is already saturated with water vapor, can slow down the evaporation process.
