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.
What have scientist already discovered about heat and evaporation?
that the more heat u have the quicker the evaporation
Are polar climates characterized by high or low rates of evaporation?
low rates of evaporation.
Are necessary for evaporation to occur?
For evaporation to occur you need the following: Heat (energy), and water.
Does evaporation occur without a fixed temperature?
=well it has to be hot for evaporation to occur but no it doesn't have a fixed temperature!=
Does evaporation of water happen at the surface?
Evaporation occur at the surface of water.
What is necessary for evaporation to occur?
Heat, or energy, is needed for evaporation to occur. Energy breaks bonds holding water molecules together, making evaporation possible.
When does most evaporation occur?
after it rains
How does evaporation occur in a fridge?
It can't.
Does evaporation occur in the freezer?
no it doesnt
Does evaporation occur in the fridge?
yes, it does
How are evaporation and condensation connected to the water cycle in nature?
Condensation occur after evaporation.
Does evaporation need hot or cold water?
Evaporation occur at any temperature but a high temperature favors evaporation.
Does condensation precipitation and evaporation occur in the stratosphere?
No
Where can evaporation occur?
ocean rivers lakes
