Answer:
Evaporation, the process by which an element or compound transitions from its liquid state to its gaseous state below the temperature at which it boils; in particular, the process by which liquid water enters the atmosphere as water vapour.

Your Answer is given below
Evaporation:
- Evaporation is the changing of a liquid into vapours (gaseous state) from the surface of the liquid without heating it.
Factors of Evaporation:
Evaporation takes place at all temperature from the surface of a liquid. The rate of evaporation is affected by various factors.
TEMPERATURE:
- At higher temperature, more molecules of a liquid are moving with high velocities. Thus, more molecules escape from its surface. Thus, evaporation is faster at high temperature than at low temperature
SURFACE AREA:
- Larger is the surface area of a liquid, greater number of molecules has the chance to escape from its surface.
WIND:
- Wind blowing over the surface of a liquid sweeps away the liquid molecules that have just escaped out.This increases the chance for more liquid molecules to escape out.
NATURE OF THE LIQUID:
- Liquids differ in the rate at which they evaporate.
