Answers:


I. (i) Rain

(ii) liquid

(iii) water

(iv) colorless

(v) condensation


II. (i) Ice is the solid state of water. When we freeze the water in our refrigerator after sometime the water change into the solid form i.e. ice.

(ii) Water vapour is the gaseous form of water. Small water drops combine together to form clouds.

(iii) The heat of the Sun warms the water in the rivers, ponds, etc., and forms water vapour and the water vapour mixes with the air and goes high up in the atmosphere where the air is cool. In the presence of cool air, it condenses to form small water drops these water drops combine together and form clouds. When these clouds pass through the very cool air then the water drops become big and heavy these heavy and big water drops come on the Earth in the form of rain. Some of the rain water goes under the ground while most of the rain water flows and fills the rivers, ponds, etc. again.

This water again evaporates by the heat of the Sun. It again goes up and rains. This process is known as water cycle.

(iv) The conversion of water into water vapour is called evaporation and the conversion of water vapour into water drops is called condensation.


III. (i) liquid

(ii) solid

(iii) water vapour

(iv) evaporation

(v) condensation
