Condensation is basically a fancy word for the sweat that forms on a cold can of soda. However, it also refers to the actual physical transformation that takes place to generate that layer of dew. Here's how it works: the air that surrounds us is full of moisture, which is just water in gaseous form. When air cools, the relative humidity rises, saturating the air with more and more moisture. If cooled enough, the moisture actually shifts from its gaseous state back into a liquid, which then gathers on the surface of surrounding objects.
The conversion of a substance (as water) from the vapor state to a denser liquid or solid state, usually initiated by a reduction in the temperature of the vapor.
Condensation comes from the moisture in the air, and is caused by too much moisture in the air for a certain temperature. Condensation forms when warm, moist air touches a surface that is colder than the dew point of the warm air. As that air becomes colder and its temperature drops below its dew point, it must release excess moisture to reach its new, lower dew point. It releases moisture in the form of water, which appears on the colder surface.
