Natural process for evaporation and condensation

 During rains, a lot of water falls from the sky. Sometimes, the rain continues for hours. Where does so much water come from?

For this experiment, it would be better if you could procure one aluminium kettle

for boiling the water.

Otherwise, any vessel can serve the purpose. Cover it with a lid in such a way that there remains a little gap between the lid and the vessel for the exit of the steam. Now boil the water till the steam starts coming out. Take some pieces of ice or chilled water in a pan with a handle.



Now see from where the rain water comes in the sky. Hold the pan at some distance from the nozzle of the kettle blowing out the steam and see what happens. The hot steam strikes the outer chilled wall of the pan and gets converted again into water drops, i.e., the process of condensation takes place. When many such drops combine together and become too heavy to withstand their own weight, they start falling to the ground. This precisely is the process by which the rain falls.

The heat emanating from the sun converts the water of the rivers, lakes and the seas into vapour and thus, water in the form of vapour gets absorbed in the atmosphere. As the air ascends, it becomes colder and the vapours present in it take the shape of tiny drops of water owing to the colder climate above. A large collection of such water drops forms the cloud. When the water drops in the cloud become too heavy to withstand their own weight, they start falling to the earth and thus, we get the delight of rains.
