Physics for IGCSE & O level - Thermal Effects (Section 3 - No. 4)
If you increase the humidity, what happens to the rate of evaporation?
Evaporation increases.
Evaporation decreases.
Evaporation stays the same.
Evaporation does not happen.
Explication
Higher humidity means there is more water vapor already in the air, and thus evaporation is reduced.
