Difference Between Evaporation and Boiling - Definition and FAQs

Difference Between Evaporation and Boiling

Evaporation is a natural process that occurs with the help of heat energy provided by sunlight and results in the liquid to convert to gaseous form during the rise in pressure or temperature and liquid is heated up in boiling by an external medium i.e. we need to give proper energy externally for this process and because of the constant heating of the liquid, it is vaporized the liquid.

As evaporation is a surface phenomenon, evaporation takes place on liquid’s surface. When being heated up generally through sunlight whereas boiling usually occurs within the whole body of the liquid or water that gets heated up. We can’t observe the Bubbling effect in evaporation but we can observe the Bubbling effect in the boiling process. In general, evaporation is a slow process as it depends on heat transferred due to sunlight and is more carried out when compared to boiling whereas The process of boiling is usually much faster and the process happens quite rapidly as well because we will provide external energy in this process.

Evaporation kid Friendly Definition

In our surroundings, there are many bodies of water like lakes, oceans, rivers, ponds, etc. If we provide heat to these bodies then what will happen! Simply we can say that water will get hotter or warmer I.e. there will be change in temperature and if the temperature increasing rapidly then a till coming when its state will going to be changed and at that point, we can observe that water is changing to vapour and moving upwards. That’s it changing of state of water from one form to another in the presence of heat or sunlight is called evaporation.

Or when liquid will turn into gas or vapour then it is known as evaporation. A common An example of evaporation includes water from soil that gets converted into vapour through the continuous heating effect of sunlight. Evaporation is a slow process and this process can occur without interference it’s boiling I.e. No need to attain boiling point for evaporation it can also occur below its boiling point

Types of Evaporation

We can easily observe examples of evaporation in our surrounding

Like when we dry clothes under the sunlight,

When we do ironing of clothes,

Ice cubes are melting due to evaporation,

In the formation of common salts, evaporation plays a very important role,

Evaporation of nail paint remover I.e. thinner

Evaporation is responsible for many drying activities like drying of hairs, drying of water bodies like oceans, lakes, rivers, ponds, etc.

In our body evaporation is the one who makes us feel cool due by converting sweat into vapour.

In comparison to boiling, we can easily observe that boing is a fast process. In this process, we heat a substance to attain its boiling point, at its boiling point the substance range its state from liquid to vapour generally. In boiling, there is a major role of boiling point as substance generally liquid must need temperature more that it’s the boiling point for this process. One more important difference between these two Is that evaporation is a surface phenomenon I.e. it will occur on the surface of a substance whereas boiling can occur through the entire mass I.e. large mass of the substance.
