Question

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

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

Answer 1

The correct option is B Insoluble heavy impurities

Evaporation is the process by which liquid turns into gas. Factors affecting the rate of evaporation are:
(i) wind speed
(ii) temperature
(iii) surface area
The insoluble impurities are going to stay in the solution and hence will not affect the process of the evaporation of the solvent from the solution.
