What are the merits and demerits of evaporation of liquids?

Answer 1

Evaporation is essential for the water cycle that brings rain. It is a slow process in nature which brings humidity in the atmosphere. It helps in heat transfer. However, evaporation also makes the water level to dry up, especially in dry areas, where it is essential.

Answer 2

Merits of evaporation of liquids include the separation of components in a mixture based on their boiling points, such as in the distillation process. It is also an effective method for concentrating solutions or suspensions. However, a demerit is that it can be a slow process, especially for large volumes of liquid, and there may be losses of volatile components during evaporation.
