Vaporization

In chemistry, vaporization describes the process by which a substance transitions from its liquid or solid state directly into a gaseous (vapor) state. This phase change occurs when the molecules within the substance gain sufficient kinetic energy to overcome the attractive intermolecular forces—the forces that hold them together in the condensed phase. Vaporization manifests in several ways, most commonly through evaporation and boiling. Evaporation is a surface phenomenon that occurs at all temperatures, while boiling is a more vigorous process that happens only when the vapor pressure of the liquid equals the surrounding atmospheric pressure. Understanding these mechanisms is crucial for comprehending various chemical and physical processes.
