Question

The rate of evaporation will not change if we change the area of the surface of the container in which the liquid is kept.

• A. True
• B. False

Answer 1

The correct option is B False

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.

Surface Area: As the surface area increases, the rate of evaporation also increases as evaporation is a surface phenomenon.

Conclusion: Hence, the given statement is false.
