Final answer:
Condensation is the conversion of a gas to a liquid, resulting in a much greater density. It plays a crucial role in the water cycle and is important in various natural and synthetic processes.
Step-by-step explanation:
Condensation is the conversion of a gas to a liquid, resulting in a much greater density. This process significantly reduces the dispersal of matter, as the molecules occupy a much smaller volume after condensing. For example, when gaseous water is cooled sufficiently, the attractions between H₂O molecules allow them to come together and form liquid water. Condensation is important because it plays a crucial role in the water cycle, where water vapor in the atmosphere condenses to form clouds, rain, and other forms of precipitation.
