Question

Which of the following does not affect evaporation?

• A. Surface area
• B. Nature of vessel
• C. Temperature
• D. Humidity

Answer 1

The correct option is B

Nature of vessel

Explanation for correct option:-

Option (b) Nature of vessel, Evaporation does not depend upon the nature of the vessel as it has nothing to do with the nature of the vessel.

Explanation for the incorrect option:-

Option (a) Surface area,

The rate of evaporation depends upon the surface area of the container in which the liquid has been poured. If the surface area increased the rate of evaporation is also increased.

Option (c) Temperature,

• The liquid molecules overcome the intermolecular force of attraction by increasing their energy and escaping into the atmosphere as a gas.
• As a result, the higher the temperature of the liquid, the faster the rate of evaporation.

Option (d) Humidity,

• The lower the relative humidity, the drier the air and the greater the rate of evaporation.
• The higher the humidity, the closer the air is to saturation, and less evaporation is possible.

Hence, Option (b) is correct, the nature of the vessel does not affect evaporation.
