Question

What is evaporation mean

Answer 1

evaporation means the different process

Answer 2

Heya!!

Here is your answer.

There are many types of changes, such as :

✨Evaporation

✨ Condensation

✨Freezing

✨Melting

✨Expansion

✨Contraction

✨Sublimation

Now,let me classify evaporation to you.

⭐The process by which a liquid changes to its gaseous form is known as evaporation.

Now,let me explain you what is evaporation with an example .i.e. water.

⭐When water is heated intensely, it turns into water vapour.This process is known as evaporation.

Now, for your convenience, just remember these so that you understand better.

⭐ Evaporation can never occur in the absence of heat.

⭐The time required for a liquid to evaporate, depends on its boiling point.

⭐The boiling point of water is 100°C and that of alcohol is 78.34°C.From this statement, it's clear that the boiling point of water is more than alcohol.This means that water will take more longer to evaporate than alcohol.Hence,proved that different types of liquids evaporate in variable time.

⭐ Evaporation causes cooling.When we heat water, the hot air molecules rise up and leave an empty space.To fill up that space, the cold air molecules come there.We know that the cold air molecules are heavier than the hot omes.So, the cold air molecules stay at the bottom. I hope it's clear that why evaporation causes cooling.
