Question

How surface area and speed of wind affects the rate of evaporation? Exaplain

Answer 1

Evaporation increases with an increase in the surface area

If the surface area is increased, then the amount is of liquid that is exposed to air is larger. More molecules can escape with a wider surface area. For e.g. We spread out clothes to dry. We do that because that speeds up the process of vaporization.

Evaporation increases with an increase in the speed of wind

Particles of vapor move away when the speed of wind increases. This leads to a decrease in the amount of water vapor in the atmosphere. For example, we use hand dryers to dry our hands. Here the wind is expelled from the hand dryer which dries our hand.
