Condensation definition types and examples are listed here. After identifying the physical states of materials, it is worth noting that some substances have the ability to transfer from one physical state to another, which is the best example of condensation, where the definition of condensation and its types will be touched, where condensation is defined as the process in which water is diverted from the state Gaseous to the liquid state, as this process is the opposite of evaporation, in which liquid water is converted to steam, while the condensation process occurs in one of two ways, either the air cools to the dew point, or it reaches the degree of saturation with water vapor, even He cannot hold pain The hands of the water.

Condensation types

After the definition of condensation, its types should be indicated, where the condensation process occurs in more than one form, depending on several factors, including: temperature and pressure, and these forms can be relied upon by classifying this process into the following types:

[1] Dew

Condensation in the form of dew drops occurs when water vapor is exposed to a relatively cool surface, where its temperature is less than the temperature of the dew point, which is expressed as the temperature at which the air cools, the pressure is constant, and water vapor is constant, where the saturation state of water is reached .

[2] Frost

The term frost is used to express ice crystals that are formed by the deposition of water vapor on the cold surfaces of objects, and this occurs specifically when the body temperature is lower than the temperature of the frost point, where the temperature of the frost point is expressed to the degree that the moist air cools at a constant pressure and water vapor The constant for reaching saturation with respect to ice, and differs from the dew point temperature is that it is lower than it where it reaches 0 degrees Celsius or less.

[3] The fog

Fog occurs when water droplets or ice crystals are suspended in the air layer at a low altitude from the surface of the earth , which leads to obstruction or reduced vision to 1000 meters or less, and the most important reason for their occurrence is night radiative cooling, as it works to cool the air near the surface The Earth to a temperature below the dew point temperature, and it appears as a cloud covering the Earth’s surface.
