Evaporation is a spontaneous phenomenon. The molecules in the liquid possess kinetic energy. All the molecules donot possess the same kinetic energy. The molecules with higher kinetic energy are on the surface of liquids. They can readily overcome the intermolecular attractions and escape into the atmosphere. This phenomenon is known as evaporation. As the molecules with higher kinetic energy keep on escaping the whole kinetic energy of the liquid is lowered. Since energy is directly proportional to temperature. Thus evaporation causes cooling effect.

3 examples of evaporation?
Evaporation refers to the process of becoming vapor. Evaporation occurs when the sun heats up the earth surface. Evaporation also occurs when water is heated in a cooking vessel.
What conditions will increase the rate of evaporation?
Heat speeds up the rate of evaporation.
Why does salt slow evaporation?
The evaporation of water is slow when water is dissolved in salt. This is because of the salt molecules, the salt molecules is the reason for the slow evaporation.
Are polar climates characterized by high or low rates of evaporation?
low rates of evaporation.
What have scientist already discovered about heat and evaporation?
that the more heat u have the quicker the evaporation
