What is Evaporation
Evaporation is a process where the liquid on the surface level gets vaporized. In the process of evaporation, the heat energy on the molecules makes them active. This in turn forces to collide to each other and thus evaporates to the atmosphere. Given gas is the term which is referred to those liquids which do not undergo evaporation at a certain given temperature. These given gas liquids take more time to evaporate when compared to other liquids. But, evaporation occurs in all liquids at varying degrees.
Evaporation is a very important phenomenon for the life on earth, as it is responsible for the water cycle. The distribution of water across the earth from oceans, lakes to the land through rain is caused by the water cycle. There won’t be any plants which exist in the absence of water cycle due to the lack of distribution of water. There are many factors which are responsible for the pace of evaporation. Some of the factors responsible are mentioned below: –
- The concentration of the substance in the air matter for the rate of evaporation. In places where the air is completely moist, the rate at which the process of evaporation occurs is slow. This process of evaporation would be slow even in the presence of other particles in the air.
- Sometimes, there could be multiple mixtures of liquids. In this case, due to the presence of other particles, the evaporation of these liquids would be slow.
- The rate at which the air flows also has an influence on evaporation. The evaporation would happen at a faster rate, when fresh air keeps blowing on the water continuously. This in turn increases the substance present in the air which reduces the rate of evaporation in the further stages.
- The molecules which are present in a liquid take more time to escape in case the intermolecular forces between the molecules are more.
- The pressure also plays a role in faster evaporation. When the pressure exerted on the surface areas of the liquid is less, the evaporation is faster.
- If you wish to evaporate a particular quantity of liquid quickly, the technique is to keep liquid on a large surface. This makes the process of evaporation faster.
- Temperature of a liquid matters for evaporation. When the temperature is high, the molecules get charged and thus escape. This temperature varies from one liquid to another. Even if the density of the liquid is high, the evaporation would be slow.
These are the various factors that influence the process of evaporation on earth. Evaporation is a natural and a well planned mechanism created by nature.
