Question

Which of the following does not affect the rate of evaporation?

• A. Wind speed
• B. Surface area
• C. Temperature
• D. Insoluble heavy impurities

Answer 1

The correct option is D Insoluble heavy impurities

Factors affecting rate of evaporation:

• Temperature: As the temperature increases, the rate of evaporation also increases. Temperature and rate of evaporation are proportional to each other.
• Surface area: As the surface area increases, the rate of evaporation increases. The surface area and rate of evaporation are proportional to each other.
• Humidity: The rate of evaporation decreases with an increase in humidity. Humidity and the rate of evaporation are inversely proportional to each other.
• Wind speed: Increase in wind speed results in increased evaporation. Wind speed and rate of evaporation are proportional to each other.
