The process of converting a liquid into a gas is known as evaporation. This occurs when molecules in the liquid gain enough energy to break free from the liquid's surface and enter the gaseous state. Evaporation is a crucial part of the water cycle, contributing to the formation of clouds and precipitation. Factors such as temperature, surface area, and air movement can accelerate the rate of evaporation. For instance, heat increases molecular energy, prompting more molecules to escape. Evaporation contributes to various natural processes, including cooling effects in nature and human activities like drying clothes.
