Water condenses into water vapor after evaporating from a cup of hot tea

The term of condensation is also used in chemistry see Condensation (organic chemistry) and Condensation reaction and the term condensate is also used in particle physics where it describes a particular state of matter. A condensation reaction is a Chemical reaction in which two Molecules or moieties ( Functional groups) combine to form one single molecule together with A condensation reaction is a Chemical reaction in which two Molecules or moieties ( Functional groups) combine to form one single molecule together with Particle physics is a branch of Physics that studies the elementary constituents of Matter and Radiation, and the interactions between them

Condensation is the change of the physical state of aggregation (or simply state) of matter from gaseous phase into liquid phase. ^[1] When the transition happens from the gaseous phase into the solid phase directly, bypassing the liquid phase the change is called deposition, which is the opposite of sublimation.

Condensation commonly occurs when a vapor is cooled to its dew point, but the dewpoint can also be reached through compression. The dew point (sometimes spelled dewpoint) is the Temperature to which a given parcel of Air must be cooled at constant Barometric pressure, The condensed vapour is called a condensate, the laboratory or the industrial equipment used for condensation is called a condenser. For other Condensers not involving heat transfer see Condenser (disambiguation

The science of studying the thermodynamic properties of moist air and the interrelationships between these in order to analyze, and predict properties by changing in the conditions of moist air is called psychrometry. Psychrometrics or psychrometry are terms used to describe the field of engineering concerned with the determination of physical and thermodynamic properties of gas-vapor mixtures The interrelationship can be graphically represented, and prediction carried out graphically by the psychrometric chart Most people think the water is condensation, but condensation is only the process of change. Psychrometrics or psychrometry are terms used to describe the field of engineering concerned with the determination of physical and thermodynamic properties of gas-vapor mixtures

Condensation in buildings

Condensation is the most common form of dampness encountered in buildings. In buildings the internal air can have a high level of relative humidity due to the activity of the occupants (e. g. cooking, drying clothes, breathing etc. ). When this air comes into contact with cold surfaces such as windows and cold walls it can condense, causing dampness. ^[2] Condensation is change from a gas to a liquid. Condensation is when water vapor cools to a liquid.

Applications of condensation

Condensation is a crucial component of distillation, an important application in laboratory and industrial chemistry application. Distillation is a method of separating Mixtures based on differences in their volatilities in a boiling liquid mixture

Because condensation is a naturally occurring phenomenon, it can often be used to generate water in large quantities for human use. In fact, there are many structures that are made solely for the purpose of collecting water from condensation, such as fog fences, air wells and dew ponds. An air well, fog collector, or fog fence is an apparatus for collecting liquid Water from Fog, using of a fine Mesh or array of parallel An air well, fog collector, or fog fence is an apparatus for collecting liquid Water from Fog, using of a fine Mesh or array of parallel Dew pond west leakejpg|thumb|Dew pond on hill above West Leake Nottinghamshire Such system can often be used to retain soil moisture in areas where active desertification is occurring. Desertification is the degradation of land in arid and dry sub-humid areas resulting primarily from human activities and influenced by climatic variations In fact, certain organizations use education about water condensers in efforts to effectively aid such areas. ^[3]
