Evaporation is when liquid escapes the surface and turns into a gas, it is an endothermic process, I believe. However, evaporation is not the same as boiling. In crystallization a solid crystallizes out of a liquid in an exothermic process. Someone please correct me if I'm wrong.

Slow evaporation can lead to crystallization of a solute.

Both evaporation and crystalization are endothermic (energy-requiring) processes. In the first, the added energy forces the molecules to leave the liquid state and become a gas; in the second, the energy loss in a solution causes some of the molecules to lineup in an orderly fashion. Evaporation takes place with any liquid, but crystalization only occurs with solutions.
