The term for the process of liquid turning into vapor is called evaporation. This occurs when molecules in a liquid gain enough energy, often through heat, to overcome intermolecular forces and transition into the gaseous state. Evaporation commonly happens on the surface of the liquid, causing gradual loss of the liquid over time. This process is influenced by factors such as temperature, surface area, and air movement. Evaporation plays a critical role in various natural processes, including the water cycle, where it contributes to cloud formation. It is also utilized in various applications, such as drying clothes and industrial processes.
