Question

Evaporation is a surface phenomenon.

• A. True
• B. False

Answer 1

The correct option is A True

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.

Factors affecting evaporation are:

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

The rate of evaporation increases as we increase the surface area of evaporation. Hence evaporation is a surface phenomenon.

Conclusion: Hence the given statement is true.
