Definition - What does Vaporization mean?

Vaporization is a phase transition of an element or compound from liquid to vapor form. As the word suggests “vaporization” means turning into vapor. In simple words, it just means turning into gas, when boiling water turns into steam and rises into the atmosphere. For the process of vaporization to start heat is very important. The atoms or molecule of a liquid is held together by cohesive force and heat loosens this force resulting in separation of atoms and molecules into vapors. The two types of vaporization are evaporation and boiling. Boiling is a bulk phenomenon whereas evaporation is surface phenomenon.

Petropedia explains Vaporization

Vaporization refers to the physical destruction of an object that is exposed to intense heat. Vaporization is mainly of two types Evaporation and boiling. Evaporation is a phase transition from liquid to vapor that occurs at a temperature lower than the boiling temperature at a given pressure. Evaporation only occurs when the equilibrium vapor pressure is more than the partial pressure of the vapor. Boiling is also a phase transition from liquid to gas but it is the formation of bubbles below the surface of the liquid. Boiling occurs when the environmental pressure is less than or equal to equilibrium vapor pressure of the substance.
