What is condensation?

 When you pour some cold (chilled) drink into a tumbler, you will find some droplets shining on the outer side of the tumbler, however, carefully you pour it. Do you know why it so happens?

Take a tumbler and fill half of it with water. Now put some ice-cubes into it and wait for sometime. The ice will melt and start cooling the water as well as the tumbler.

After a while, you will find that the outer wall of the tumbler—so far quite clean—has now some shining droplets of water on it. Where have these droplets come from on the outer wall of the tumbler? Also, you will notice that the warmer the surroundings, the more quickly the droplets will shine on the outer side of the tumbler and in greater number.

You have already understood the process of evaporation by earlier experiments. On all open water surfaces, this process goes on; the process in which water changes to vapour form and gets absorbed in the atmosphere. But whenever it comes into contact with a cool surface, it comes back into the liquid form like the droplets you saw on the tumbler. This subsequent process is known as condensation.

With the increase in temperature, the process of evaporation also speeds up. Similarly, the process of condensation is also faster if it takes place on a cooler surface
