Which one of the following statements is not correct?
general-sciencechemistry
- AThe rate of evaporation depends on temperature
- BThe rate of evaporation does not depend on surface area exposed to the atmosphere but on volume of the liquid
- CThe rate of evaporation depends on humidity of the surroundings
- DThe rate of evaporation depends on the wind speed
Explanation
The rate of evaporation increases with the surface area exposed to the atmosphere (more molecules can escape), so statement (B), which denies any role for surface area and credits only volume, is not correct. Evaporation genuinely depends on temperature, humidity, and wind speed, making (A), (C), and (D) correct statements.
