Condensation is the process where water vapor i do not care liquid. That is the reverse of evaporation, wherein liquid water i do not care a vapor.Condensation happens among two ways: either the air is cooled to its dew suggest or it becomes so saturated v water vapor the it cannot organize any more water.

Dew PointDew suggest is the temperature at which condensation happens. (Dew is merely condensed water in the atmosphere.) air temperatures have the right to reach or fall below the dew suggest naturally, together they regularly do at night. Thats why lawns, cars, and houses are regularly coated v water droplets in the morning.Condensation can likewise produce water droplets on the exterior of soda cans or glasses that cold water. When warm air access time the cold surface, the reaches the dew suggest and condenses. This leaves droplets that water ~ above the glass or can.When a bag of wait becomes full of water vapor, clouds form. The allude at i m sorry condensation starts have the right to be easily viewed in cumulus clouds, which have flat bottoms. Those flat bottoms space where vapor starts to condense into water droplets.SaturationClouds are simply masses the water droplets in the atmosphere. Molecules in water vapor are far apart indigenous one another. As much more water vapor collection in clouds, they can become saturated v water vapor. Saturation clouds cannot hold any much more water vapor. As soon as clouds room saturated through water vapor, the density, or closeness, that the molecule increases. The vapor condenses and also becomes rain.Cold wait holds less water vapor than warm air. This is why warm climates space often an ext humid 보다 cold ones: Water vapor continues to be in the air instead of condensing right into rain. Cold climates are an ext likely to have actually rain, because water vapor condenses an ext easily there.


Making RainCloud condensation nuclei (CCN) are microscopic bits that clay, salt, or hard pollutants such as ash native smoke. Water in clouds condenses around these condensation nuclei to kind raindrops.

(atm) unit the measurement equal to air pressure at sea level, around 14.7 pounds every square inch. Likewise called standard atmospheric pressure.
