Condensation is a process in which a substance changes from a gaseous state to a liquid state. This can occur when the temperature of a gas is reduced below its dew point, causing the gas molecules to come together and form liquid droplets. Condensation is a common occurrence in everyday life, such as when water vapor in the air condenses on a cold surface to form dew or when hot steam condenses on a cold mirror. In scientific research, condensation is studied in various fields such as atmospheric science, chemistry, and physics to better understand the behavior of gases and liquids under different conditions. Research in condensation often focuses on factors such as temperature, pressure, and surface properties that influence the condensation process.
