From Wikipedia, the free encyclopedia
Water vapor, also aqueous vapor, is the gas phase of water. On the Earth, water vapor is one state of the water cycle within the hydrosphere.[2] Water vapor can be produced from the evaporation of liquid water or from the sublimation of ice. Under normal atmospheric conditions,[3] water vapor is continuously evaporating and condensing. Normally, we think water vapor is invisible to the naked eye. But the Tyndall effect shows us that our atmosphere is a largely varying colloid of air and vapor. For example, the Tyndall effect is most noticeable when car headlamps are used in fog due to the amount of light scattering.
