Any matter in this universe has three forms Solid, Liquid & Gas, and all these matter is composed of atoms these atoms are held together by a bond. It may be a Covalent or a Electrovalent Bond... So there is some kind of force that keeps these atoms together.
A matter is in solid form because the bonding between the atoms is strong so if we supply enough energy to break this bond solid becomes liquid, if even more energy is supplied it becomes gas.
Thats Y when we supply energy in form of heat to water it breaks the bond and becomes free hence becomes gas(vapor)..
More info...
There exists a covalent bonding in water molecule..
Covalent bond is weaker than the electrovalent bond

The meaning of evaporation is when a liquid turns into a gas due to heat energy allowing the atoms to escape. However, when levels of heat energy decrease, the gas cools down, thus condensing or turning into a liquid. For example as the tea cools, the water vapor condenses. An example of both condensation and evaporation is a nuclear reactor which smashes the molecules, produces heat energy to heat the water and turns it into water vapor by evaporation to move turbines and when the water vapor moves out of the turbines it condenses. Another example of both is when you have a shower or a bath. When the water in the bathtub heats, it starts to evaporate but when it comes in contact with the cooler surface of the mirror it condenses.

My guess as a commoner who does not specialize in science is:
Water evaporates when the energy of the water molecule is high enough to escape the liquid form. Usually this is because of heat, but I think it is sometimes also because of pressure (dry ice).

Evaporation or vapor phase (state) of water is a function of how close together the molecules are and this is affected by temperature and pressure. At STP (standard temperature and pressure) H2O is in liquid phase.
See http://www.lsbu.ac.uk/water/phase.html for a diagram of the phases of water at various temperatures and pressures.
There are more than three states of matter (phase).
Solids
Liquids,
Gases,
Plasmas (as in Plasma TV)
Quark-Gluon Plasmas,
Bose-Einstein condensates
Fermionic condensates
Strange matter
Liquid Cystals (as in LCD displays)
Superfluids
