Question

Vaporization is an endothermic process. Using the terms 'kinetic energy' and 'intermolecular forces', explain how the addition of energy can cause a liquid to vaporize.

Answer 1

An endothermic process is a process that needs energy in order to proceed. This is the opposite of exothermic which is a process of releasing energy. During an endothermic process, the temperature of the system is increased thus exciting the molecules and allowing them to move faster. This will cause liquid to vaporize.
