The NCERT Solutions in English Language for Class 6 Science<\/a><\/span> Chapter – 14 (Water) <\/strong>has been provided here to help the students in solving the questions from this exercise.<\/span><\/p>\n

Chapter – 14 (Water)<\/span><\/strong><\/span><\/h2>\n

1. Fill up the blanks in the following:
\n<\/strong>(a) The process of changing of water into its vapour is called _________________.
\n(b) The process of changing water vapour into water is called _________________.
\n(c) No rainfall for a year or more may lead to _________________ in that region.
\n(d) Excessive rains may cause _________________.<\/span><\/p>\n

Answer –\u00a0<\/strong><\/span><\/p>\n

(a) The process of changing of water into its vapour is called\u00a0evaporation<\/strong><\/span>.
\n(b) The process of changing water vapour into water is called\u00a0condensation<\/strong><\/span>.
\n(c) No rainfall for a year or more may lead to\u00a0drought<\/strong><\/span>\u00a0in that region.
\n(d) Excessive rains may cause\u00a0floods<\/strong><\/span>.<\/span><\/p>\n

2. State for each of the following whether it is due to evaporation or condensation:
\n<\/strong>(a) Water drops appear on the outer surface of a glass containing cold water.
\n(b) Steam rising from wet clothes while they are ironed.
\n(c) Fog appearing on a cold winter morning.
\n(d) Blackboard dries up after wiping it.
\n(e) Steam rising from a hot girdle when water is sprinkled on it.<\/span><\/p>\n

Answer –\u00a0<\/strong><\/span><\/p>\n

(a) Condensation
\n(b) Evaporation
\n(c) Condensation
\n(d) Evaporation
\n(e) Evaporation<\/span><\/p>\n

3. Which of the following statements are \u201ctrue\u201d ?
\n<\/strong>(a) Water vapour is present in air only during the monsoon. ( )
\n(b) Water evaporates into air from oceans, rivers and lakes but not from the soil.( )
\n(c) The process of water changing into its vapour, is called evaporation.( )
\n(d) The evaporation of water takes place only in sunlight.( )
\n(e) Water vapour condenses to form tiny droplets of water in the upper layers of air where it is cooler.( )<\/span><\/p>\n

Answer –\u00a0<\/strong><\/span><\/p>\n

(a) Water vapour is present in air only during the monsoon. (False)<\/strong>
\n(b) Water evaporates into air from oceans, rivers and lakes but not from the soil. (False)<\/strong>
\n(c) The process of water changing into its vapour, is called evaporation. (True)<\/strong>
\n(d) The evaporation of water takes place only in sunlight. (False)<\/strong>
\n(e) Water vapour condenses to form tiny droplets of water in the upper layers of air where it is cooler. (True)<\/strong><\/span><\/p>\n

4. Suppose you want to dry your school uniform quickly. Would spreading it near an anghiti or heater help? If yes, how?<\/strong><\/span><\/p>\n

Answer –\u00a0<\/strong>Yes,\u00a0Spreading uniform near an anghiti or heater will help because it increases the rate of evaporation due to heat.<\/span><\/p>\n

5. Take out a cooled bottle of water from refrigerator and keep it on a table. After some time you notice a droplets of water around it. Why?<\/strong><\/span><\/p>\n

Answer –\u00a0<\/strong>The air around the cooled bottle of water gets cooled and water vapour present in it condenses into the water which collects as a puddle of water around the bottle.<\/span><\/p>\n

6. To clean their spectacles, people often breathe out on glasses to make them wet. Explain why the glasses become wet.<\/strong><\/span><\/p>\n

Answer – <\/strong>When we breathe out, water vapour also comes out with exhaled air. This water vapour when comes in contact with the glasses of spectacles makes them wet.<\/span><\/p>\n

7. How are clouds formed?<\/strong><\/span><\/p>\n

Answer –\u00a0<\/strong>When the air containing water vapour moves up, it gets cooler and cooler. At sufficient heights, the air becomes so cool that the water vapour present in it condenses to form tiny drops of water called droplets. It is these tiny droplets that remain floating in the air and form clouds.<\/span><\/p>\n

8. When does a drought occur?<\/strong><\/span><\/p>\n

Answer –\u00a0<\/strong>Drought occurs when it does not rain for a long period.<\/span><\/p>\n
