Why Does Water Evaporate Before Its Boiling Point?

It is important to understand that evaporation and boiling are two different processes. Evaporation is the process that takes place at the surface of the liquid and can happen at any temperature whereas boiling is taking place under specific conditions and is a bulk transformation.

When boiling takes place, the intermolecular bonds in water are broken and not the bonds between hydrogen and oxygen atoms. This breakage of bonds can happen only at certain temperatures.nnWhile in evaporation few molecules manage to escape from the surface to the air.
