The vapour goes up and forms the clouds .We get rain from the clouds so the water vapor is very useful to us . On cooling ,the water vapour turns in to water .

15. The change of water vapor into water is called condensation
The change of water vapor into water is called condensation . The water in the liquid from is very useful to us. On cooling, water changes in to ice. The water in the ponds and lakes changes into ice in winter in cold countries. Water can be changed into ice by keeping it in the freezer of a refrigerator.
