Examples of Evaporation

Evaporation is a physical process by which a liquid gradually increases its temperature until it becomes vapor, for this the temperature in question is increased through natural or artificial processes. The water molecules are agitated by the action of heat so that they begin to increase their energy until they manage to pass into a gaseous state, a very simple example of this process in a natural way is when a container with water is left and uncovered, after a few days it will be noticed that the amount has decreased and this is because a certain amount has evaporated.

Evaporation is one of the most important stages within the water cycle or also known as the “hydrological cycle”, in nature it occurs frequently in the oceans, lakes and rivers and even on the earth’s surface where there is moisture, the heat from the sun generates enough temperature to convert the liquid into gas which rises to the atmosphere and is where it condenses and then precipitates in the form of rain, dew or snow and thus begins the cycle again.

It is important to know how to differentiate evaporation from boiling, both are different processes, in the first case being the process that occurs gradually and under any temperature level, on the other hand, boiling requires that a quantity of liquid be exposed to a specific quantity temperature and pressure , both have in common that the liquid evaporates.

Examples of evaporation

  1. Freshly washed clothes placed in the sun will dry out due to evaporation.
  2. Clouds are formed in part thanks to the evaporation of ocean water.
  3. The meals which are cooked thanks to the heat generated by the steam emanating from the liquid in conversion to a gaseous state.
  4. Dry ice when exposed to air.
  5. Sea salt which is the product of the evaporation of sea water and the residue it leaves behind.
  6. A cup of hot coffee emitting smoke, it is a certain amount of liquid evaporating.
