The process of converting liquid into gas is called evaporation. During evaporation, molecules at the surface of the liquid gain enough energy, typically from heat, to overcome intermolecular forces and transition into the gas phase. This process can occur at various temperatures, even below the boiling point of the liquid. Evaporation is a significant aspect of the water cycle, contributing to weather patterns and the distribution of moisture in the atmosphere. It also has several practical applications in everyday life, such as drying clothes and cooling surfaces through sweat evaporation.
