What is the process called when water vapor turns into liquid water?

The process when water vapor turns into liquid water is called condensation. This occurs when water vapor in the air cools down and loses energy, causing the molecules to come together and form liquid droplets. This is a key part of the water cycle and can be observed in everyday life, such as when dew forms on grass in the morning or when water droplets gather on the outside of a cold glass.

Understanding this process is essential because it plays a crucial role in weather patterns, cloud formation, and the overall movement of water in the environment.
