Question

.....……is a surface phenomenon.

Answer 1

• Evaporation is a process in which the liquid changes to vapours even below its boiling point. This process requires heat energy.
• For example, common salt is obtained from the sea using the process of evaporation, drying of clothes, etc.
• Evaporation is a surface phenomenon as it increases by increasing the surface area of the liquid.

Hence, Evaporation is a surface phenomenon.
