Learn what condensation means in chemistry, with simple explanations, real-life and exam examples, and how it differs from evaporation and precipitation. Condensation is the process in which water vapour cools down to become liquid. Condensation in Chemistry can be viewed as the reverse process of evaporation, where liquid water heats and acquires vapour form. Condensation occurs when any of the two conditions come true, i.e., the air is cooled to its dew point or it becomes so saturated with water vapour that it cannot hold any more water. Condensation transforms water vapour into liquid water. In this article, we will learn what is ... Condensation is the change of water from its gaseous state (water vapour) into its liquid form. This occurs when water vapour cools and condenses upon contact with a cooler surface. Condensation forming in the low pressure zone above the wing of an aircraft due to adiabatic expansion Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle. [1] It can also be defined as the change in the state of water vapor to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within the atmosphere. When the transition happens from ...
