What process involves the transformation of water vapor into liquid water?

The process of transforming water vapor into liquid water is known as condensation. This occurs when the temperature of water vapor decreases, causing the molecules to lose energy and come together to form liquid droplets. This transformation is commonly observed in nature, such as when clouds form or when dew collects on grass in the morning.

Condensation plays a crucial role in the water cycle, contributing to precipitation. For example, as water vapor rises in the atmosphere, it cools and condenses into tiny water droplets, which eventually combine to form clouds. When these droplets become heavy enough, they fall to the ground as precipitation, which includes rain, snow, sleet, or hail.

In contrast, evaporation refers to the process where liquid water turns into vapor, while transpiration involves the release of water vapor from plants into the atmosphere. Thus, understanding condensation clarifies its role in both the water cycle and meteorological phenomena.
