Evaporation is the process by which liquid water transforms into water vapor, a gas. This occurs when molecules at the surface of the liquid gain enough energy, often from heat, to break free from the liquid's surface. Factors such as temperature, surface area, and air movement can influence the rate of evaporation. In nature, evaporation plays a crucial role in the water cycle, contributing to the formation of clouds and precipitation. It is also essential in various applications, including industrial processes, agriculture, and climate regulation, helping to maintain balance in ecosystems and weather patterns.
