Evaporation is the process by which water (and other liquids) changes from a liquid
state to a vapor or gas state.
FACTORS AFFECTING EVAPORATION
The rate of evaporation increases with–
• An increase of surface area:
We know that evaporation is a surface phenomenon. If the surface area is increased,
the rate of evaporation increases. For example, while putting clothes for drying up
we spread them out.
• An increase of temperature:
With the increase of temperature, more number of particles get enough kinetic
energy to go into the vapour state.
• A decrease in humidity:
Humidity is the amount of water vapour present in air. The air around us cannot hold
more than a definite amount of water vapour at a given temperature. If the amount
of water in air is already high, the rate of evaporation decreases.
• An increase in wind speed:
It is a common observation that clothes dry faster on a windy day. With the increase
in wind speed, the particles of water vapour move away with the wind, decreasing
the amount of water vapour in the surrounding.
I hope its help you.

Evaporation is when a liquid becomes a gaswithout forming bubbles inside the liquid volume. If bubbles are formed we are talking instead about "boiling".
For example, water left in a bowl will slowly disappear. The water evaporates into water vapor, the gas phase of water. The water vapor mixes with the air.
The reverse of evaporation is condensation.
When the molecules in a liquid are heated, they move faster. This makes them full of energy and so the particles collide with each other, and eventually they become so far apart that they become a gas.
