The condensation Is the process by which a substance that is in the gaseous state passes to liquid state.
This phenomenon happens thanks to a change in the pressure and the temperature of an element, causing the water vapor contained in it to become liquid water (Fennell, 2017).
Condensation can be understood as the process opposite to evaporation, where the water gas becomes liquid once it cools.
In the case of water, the dew point is exactly the same as the boiling point: 100 ° C. This means that when it reaches or exceeds 100 ° C, the water will begin to bubble and evaporate, however, when it cools and reaches 100 ° C again, it will condense again (Softschools, 2017) 1.
In this way, water condensation takes place between 100 ° C and 0 ° C. Below 0 ° C the water will freeze.
When the water condenses, the molecules that compose it are united, causing that the steam of water changes of state and turns into a liquid.
On the other hand, when the water is in the gaseous state, its molecules are dispersed in the air (BWC, 2017).
Although the condensation process is usually exemplified with water, it also occurs in alcohols, gases and other chemicals.
Outstanding examples of condensation
Clouds are a large-scale example of condensation, as they are generally formed when water vapor in hot air rises and encounters cold air in the highest part of the atmosphere. As the air cools and the water molecules approach and unite, water droplets or ice crystals form and surround the dust particles in the air. Clouds are millions of these joints of water molecules and dust particles moving together (Kattenburg, 2017).
"Rain drops are a form of condensation of water that takes place in the clouds and then fall and water the earth.
-When the lens of glasses is cloudy when opening a pot with boiling water.
"Drops of water running on the outside of a glass of ice-cold soda on a hot day. This phenomenon happens when the molecules of water vapor in the air meet the surface of the vessel and condense on it.
-When we can see the air vapor we breathe on a very cold day.
-The dew that forms on the leaves of plants during the morning hours, thanks to the presence of hot steam in the grass that cools on the surfaces of the leaves.
- When the bathroom mirror is fogged after a shower, thanks to the effect of water vapor in the same condensate on the glass surface.
-When boiling water in a closed container, it is evident how the vapor that reaches the lid of the container is transformed into droplets thanks to the condensation process.
-The frost on the outside of an ice bucket indicates that the evaporated water is condensed again on the outer surface of the bucket, leaving a film of ice.
