Question

how surface area and speed of wind affects the rate of evaporation? Explain

Answer 1

• Surface area :
Greater the surface area , greater is the rate of evaporation as more liquid will be exposed to the environment.
• Wind Speed :
Greater the wind speed , greater is the rate of evaporation as wind will quickly replace the moist air with the dry air for efficient evaporation.

Answer 2

surface area effects the rate of evaporation because evaporation is a surface phenomenon and surface area is directly proportional to evaporation so, more the surface area more the rate of evaporation.



As the wind blows, it sweeps away airborne water particles that are in the air. The humidity of the air in the region of this evaporation is reduced, which allows more water molecules to dissipate into the air. Wind can also change the vapor pressure by moving air about rapidly, thereby causing it to expand. This process creates room for extra water vapor and evaporation will continue to occur while the wind is blowing.
