उत्तर
In the free state, water occurs in the solid, liquid and gaseous states.
Solid state: A large amount of fresh water is found in the form of snow or ice.
Liquid state: Most of the water present in oceans and found in streams, rivers, lakes, ponds and springs on land is water in the liquid state.
Gaseous state: Water vapour present in the air is in the gaseous state. Water vapour condenses in the sky to form clouds. Mist and fog are also examples of water in the gaseous form.
