The process by which water vapor turns into liquid water is called condensation. This phenomenon occurs when water vapor in the air cools down and changes its state back into liquid form, often as tiny droplets. Condensation is a crucial component of the water cycle and can be seen in everyday situations, such as dew forming on grass in the morning or fog on a cold day. In meteorology, condensation plays a vital role in cloud formation and precipitation, influencing weather patterns and climate. Understanding condensation helps in various scientific fields, including meteorology and environmental science.
