  Condensation - MSN Encarta
Condensation is the result of the reduction of temperature by the removal of latent heat of evaporation, the liquid product being known as condensate.
Condensation is an important part of the process of distillation and in the operation of steam engines, where exhaust steam is converted back into water by a device called a condenser.
In chemistry, condensation is a reaction involving the union of atoms in the same or different molecules.

  Condensation - Wikipedia, the free encyclopedia
Condensation is the change in matter1 of a substance to a denser phase, such as a puppy gas (or vapor) to a liquid.
Condensation commonly occurs when a vapor is cooled to a liquid, but can also occur if a vapor is compressed (i.e., pressure on it increased) into a liquid, or undergoes a combination of cooling and compression.
Condensation of vapor into liquid is the opposite of evaporation or boiling and is an exothermic process, meaning it releases heat.

 The Water Cycle: Condensation, from USGS Water Science Basics   (Site not responding. Last check: 2007-10-21)
Condensation is crucial to the water cycle because it is responsible for the formation of clouds.
As condensation occurs and liquid water forms from the vapor, the water molecules become organized in a less random structure, which is less random than in vapor, and heat is released into the atmosphere as a result.
Condensation is responsible for the water covering the inside of a window on a cold day (unless you are lucky enough to have double-paned windows that keep the inside pane relatively warm) and for the moisture on the inside of car windows, especially after people have been exhaling moist air.

 Condensation
Condensation is the process whereby water vapour in the atmosphere is returned to its original liquid state.
In the atmosphere, condensation may appear as clouds, fog, mist, dew or frost, depending upon the physical conditions of the atmosphere.
Condensation of water vapour occurs when the temperature of air is lowered to its dew point.

 Understanding Condensation
Condensation on your windows is a warning sign that the relative humidity (the measure of water vapor in the air) in your home is too high.
When you see condensation forming on your windows it is a warning that there is too much water vapor in the air of your home or that there is insufficient air circulation next to the windows on which the condensation is occurring.
Condensation is caused by the air temperature becoming too low to hold the water vapor that is in it.

 Wealth condensation - Wikipedia, the free encyclopedia
Wealth condensation is a theoretical process by which, in certain conditions, newly-created wealth tends to become concentrated in the possession of already-wealthy individuals or entities.
According to this theory, those who already hold wealth have the means to invest in new sources of creating wealth or to otherwise leverage the accumulation of wealth, thus are the beneficiaries of the new wealth.
In their wealth condensation model Bouchard and Mezard estimate that 90% of "total wealth" is owned by 5% of the population in many rich countries.

 Condensation reaction - Wikipedia, the free encyclopedia
A condensation reaction (also known as a dehydration reaction or dehydration synthesis when water is lost) is a chemical reaction in which two molecules or moieties react and become covalently bonded to one another by the concurrent loss of a small molecule, often water, methanol, or a type of hydrogen halide such as HCl.
It may be considered as the opposite of a hydrolysis reaction (the cleavage of a chemical entity into two parts by the action of water).
Other condensations, such as the acyloin condensation are triggered by radical or single electron transfer conditions.

 Alenco || Preventing Condensation
Condensation occurs when moist air touches a surface that is colder than the dew point of the air.
A common example of condensation is the water or frost which appears on windows in cold weather.
Winter condensation and moisture problems are most likely to occur in climates where the average January temperature is 35 degrees F or colder.

 Condensation
Condensation is the fog that suddenly appears in cold weather on the glass of windows and sliding glass doors.
The fog on your windows is a form of condensation; so is the water that forms on the outside of a glass of iced tea in the summer and on the bathroom mirrors and walls after someone takes a hot shower.
Condensation usually occurs first on windows because glass surfaces have the lowest temperature of any of the interior surfaces in the house.

 Benchtest.Com - Condensation
Water was condensing on the SEPP through gaps in the insulation and dripped down on to my AGP video card.
Since the capacity of air to hold water vapor changes when the temperature changes, it follows that relative humidity depends both on the amount of water vapor in the air and on the temperature of the air.
Condensation is the forming of water from water vapor.

 condensation. The Columbia Encyclopedia, Sixth Edition. 2001-05
Condensation is the reverse of vaporization, or change from liquid to gas.
Certain natural phenomena, such as dew, fog, mist, and clouds, are the result of the condensation of water vapor in the atmosphere; the formation of dew illustrates well the fundamental principles involved in such phenomena.
As heat is removed from a gas, the molecules of the gas move more slowly, and as a result, the intermolecular forces are strong enough to pull the molecules together to form droplets of liquid.

Condensation occurs where moist air comes into contact with air, or a surface, which is at a lower temperature.
In Britain, condensation in houses is mainly a winter problem particularly where warm moist air is generated in living areas and then penetrates to the colder parts of the building.
Condensation is encouraged by poor air circulation where stagnant air pockets form (behind furniture and in cupboards) and the first evidence is often the appearance of mould growth.

 Condensation   (Site not responding. Last check: 2007-10-21)
Condensation is the conversion of water vapor to a liquid.
At a liquid - vapor interface molecules are constantly entering the liquid state from the vapor (condensation) and others are going from the liquid to the vapor (evaporation).
When there is a greater number of molecules going from the vapor to liquid state, rather than the reverse, then condensation is said to be occurring.

 15 Rules on Condensation
This is because the amount of moisture in the air being compressed is determined by the temperature and relative humidity of the inlet air that enters the compressor.
This is tempting on drain points that have a high volume of condensation, such as the aftercooler separator and the air receiver tank.
The problem is that the amount of condensation will vary according to changes in the temperatures and relative humidity of the ambient environment.

 Condensation, double glazing, replacement windows, pilkington k glass
Generally when condensation is slight, a darkening of the wall surfaces, buckling of wall paper or 'steaming up' of windows will occur, and under such conditions it could be estimated that as soon as adequate warming of the affected surfaces occurs, a complete return to normal dry conditions will take place.
Serious condensation where water actually runs does not occur very often in domestic property, but we are aware of the intermittent 'running water' experienced in such instances as bathrooms and kitchens with glazed wall tile surfaces, cold water service pipes, china cisterns and window or roof glazing.
This is still condensation, but of a type which forms where the external influence of the atmosphere overcomes the internal heating influence, thus causing moisture to form in the same way that it will form on an exposed surface.
