2. What do we understand by the term’s ‘evaporation’ and ‘condensation’?
Answer: Evaporation – change of a liquid into its vapour form is called evaporation.
Condensation – change of vapour form of a substance into its liquid form on cooling is called condensation.
3. How are clouds formed?
Answer: Water from oceans, seas and rivers, changes into vapour as it evaporates due to the heat of the sun. These water vapours rise up. As these go very high, they get cooled and condense to form tiny droplets of liquid water. In this way, clouds are formed.
4. How does rain water get impure?
Answer: Raindrops, when just formed, are the purest form of water. By the time they reach the surface of the earth, they become impure, because they dissolve many harmful gases present in air and also get dust and smoke mixed up with them.
