As air rises and cools, the water in it can 'condense out,' forming clouds. Clouds exist in the atmosphere because of rising air. All of these are examples of water leaving the vapor state in the warm air and condensing into liquid as it is cools.Īir contains water molecules. Condensation is responsible for ground-level fog, the water covering the inside of a window on a cold day, and for the moisture on the inside of car windows, especially after people have been exhaling moist air. People buy coasters to keep condensed water from dripping off their chilled drink glass onto their coffee tables. You probably see condensation in your day-to-day life! If you wear glasses and go from a cold, air-conditioned room to outside on a humid day, the lenses fog up as small water droplets coat the surface via condensation.Ĭondensation drips down this window where warm, moist indoor air collides with the cooler surface. As condensation occurs and liquid water forms from the vapor, the water molecules become more organized, and heat is released into the atmosphere as a result. Water molecules in the vapor form are arranged more randomly than in liquid water. These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface. The arrangement of water molecules changes as water changes between its gaseous ( vapor), liquid, and solid forms.

Condensation is crucial to the water cycle because it is responsible for the formation of clouds. Condensation is the process by which water vapor in the air is changed into liquid water it’s the opposite of evaporation.

The air is full of water vapor, although most of the time we can't see it. Surface runoff Condensation and the Water Cycle.

Cold climates are more likely to have rain, because water vapor condenses more easily there. This is why warm climates are often more humid than cold ones: Water vapor remains in the air instead of condensing into rain. Cold air holds less water vapor than warm air. When clouds are saturated with water vapor, the density, or closeness, of the molecules increases. Saturated clouds cannot hold any more water vapor. As more water vapor collects in clouds, they can become saturated with water vapor. Molecules in water vapor are far apart from one another. Saturation Clouds are simply masses of water droplets in the atmosphere. Those flat bottoms are where vapor begins to condense into water droplets. The point at which condensation starts can be easily viewed in cumulus clouds, which have flat bottoms. When a pocket of air becomes full of water vapor, clouds form.

This leaves droplets of water on the glass or can. When warm air hits the cold surface, it reaches its dew point and condenses. Condensation can also produce water droplets on the outside of soda cans or glasses of cold water. Thats why lawns, cars, and houses are often coated with water droplets in the morning. (Dew is simply condensed water in the atmosphere.) Air temperatures can reach or fall below the dew point naturally, as they often do at night. Dew Point Dew point is the temperature at which condensation happens. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation is the process where water vapor becomes liquid.
