The phenomenon where a liquid turns into vapor is known as evaporation. This process occurs when molecules at the surface of a liquid gain enough energy, often due to heat, to transition into the gaseous state. Evaporation is influenced by various factors, such as temperature, surface area, and atmospheric pressure. It plays a crucial role in the water cycle, contributing to cloud formation and precipitation. Additionally, it can be observed in everyday situations, such as when puddles dry up after rain or when clothes dry after being washed. Understanding evaporation is essential in both natural and applied sciences.
