What happens to rate of evaporation when temperature increases?

Correct answer: Increases

Evaporation is the escape of some liquid molecules from the surface into the gas state. At any temperature, molecules have different kinetic energies. When temperature increases, the average kinetic energy increases, so a larger number of surface molecules can overcome the attractive forces holding them in the liquid and escape.

As a result, the rate of evaporation increases when temperature rises, provided other important conditions such as exposed surface area, humidity, and wind remain comparable. This is why wet clothes generally dry faster in warm conditions than in cold conditions. Option A is correct. Heating does not make evaporation zero or necessarily keep it unchanged; it supplies more energetic molecules for surface escape.
