Learn about condensation , the process of matter changing from gas to liquid, and its role in the water cycle and organic chemistry. Find out the factors that affect condensation and practice problems with solutions. Condensation Definition Condensation changes the state of matter from gaseous to liquid, often accompanied by a decrease in volume. It occurs when a vapour (gas) comes into contact with a surface that transfers heat to it and causes the vapour to cool and become denser. This process results in liquid droplets containing small amounts of dissolved materials. Condensation is often confused with evaporation which is the opposite of changing from a liquid to a gas by gaining heat. However ... Condensation is the process where water vapor cools and turns into liquid droplets. It occurs when warm air meets a cold surface. Water condensation is everywhere around us, from the glistening dew drops on grass to the fluffy clouds drifting by. It's the simple yet profound process where water vapor transforms back into liquid water. This fundamental change shapes our weather, drives the global water cycle, and influences our everyday lives in countless ways. This article from thedailyECO explores what water condensation is, how it works, and provides everyday examples, as well as its crucial role in the water cycle.
