What is evaporation? What are the factors affecting it?

Evaporation is known as the process of water changing from liquid to gas or vapour. As in it occurs on the surface of a liquid when it turns into the gaseous phase. It is an endothermic process when the heat is absorbed. The factors affecting evaporation are as follows: The wind is a critical factor of evaporation as in the wind, for example, dry the clothes faster, under a fan or when the weather is windy. As stated earlier, heat is known to affect evaporation, just like how the clothes dry faster during summer too. Humidity as in dryness assists here also. The factor of the nature of liquid also matters in evaporation, kerosene or petrol is known to evaporate faster than water. An interesting factor called the vapour pressure is applied on the liquid, as one would observe in the example of a pressure cooker. Here the pressure plays a critical role. To sum up, wind or air interactions drive the evaporation process, and it is a known reason to happen at any given temperature. Even the frost-free option in the freezer is a matter of evaporation, as in it is called the sublimation process. Adding to this, Humidity is also a critical factor. read less

The rate of evaporation is affected by the following factors: i. Temperature: The rate of evaporation increases with an increase in temperature. ii. Surface area: The rate of evaporation increases with an increase in surface area. iii. Humidity: The amount of water vapour present in the air is called humidity. read less
