Most of Earth’s water is in liquid form. Liquid water can change into an invisible gas called water vapor, or it can freeze into solid ice or snow. Unit 1 Lesson 1 Water and Its Properties The Universal Solvent What are properties of water? The property that holds molecules of a substance together is called cohesion.

Sources of Water Water is found in rivers, seas, oceans and lakes. It is also stored underground. Ocean :- The ocean water is salty , so we can not drink it . River :- It is a channel of water. Melting snow from the mountains and rain provides water to the rivers. Rain :- When water vapour in the air cools , it falls down as raindrops.
