The process by which water vapor becomes liquid is called condensation. This phenomenon occurs when water vapor—an invisible gas—cools and transitions back into liquid form, often resulting in droplets of water. Condensation is crucial in the water cycle, as it leads to the formation of clouds and precipitation. It plays a significant role in various natural processes, including weather patterns and climate regulation. Condensation can also occur in everyday situations, such as the formation of dew on grass in the early morning or moisture on cooler surfaces.
