how does energy and intermolecular forces affect water evaporation.

Sagot :

Evaporation is a phenomenon in which atoms of substances in a liquid state obtain enough energy to change to a gaseous state. The movement caused by the temperature of the molecules must be sufficient to overcome the surface tension of the substances and achieve the evaporation process. The molecules must have enough energy to

break intermolecular interactions and go to the gaseous state. Breaking up intermolecular interactions requires energy, which is usually given through heat. Therefore, this process is an endothermic reaction.
