What is vaporization?

Vaporization is the process in which a substance transitions from its liquid form to a gaseous state. This process can occur in several ways, including evaporation and boiling, both of which allow the molecules in the liquid to gain enough energy to overcome intermolecular forces and enter the gas phase. Understanding vaporization is important, especially in fields such as cosmetology and skincare, where various products may contain active ingredients that are delivered effectively through vaporized forms. The other choices describe different phase transitions: condensation refers to gas turning back into liquid, melting is the transformation from solid to liquid, and sublimation is the direct change from solid to gas, but these do not represent vaporization.
