Class 6 Science Chapter 14 Water Textbook Exercise Questions and Answers<\/h3>\n

Question 1.
\nFill up the blanks in the following:
\na. The process of changing of water into its vapour is called ……………..
\nb. The process of changing water vapour into water is called ……………..
\nc. No rainfall for a year or more may lead to …………….. in that region.
\nd. Excessive rains may cause ……………..
\nAnswer:
\na. evaporation or vaporisation
\nb. condensation
\nc. drought
\nd. flood<\/p>\n

Question 2.
\nState for each of the following due to evaporation or condensation:
\na. Water drops are formed on the outer surface of the bottle or any container containing cold water.
\nb. Formation of steam from wet clothes while they are ironed.
\nc. Appearance of fog on a cold winter morning.
\nd. Wiping of blackboard dries it up.
\ne. Steam rising from a hot girdle when water is sprinkled on it.
\nAnswer:
\na. Condensation
\nb. Evaporation
\nc. Condensation
\nd. Evaporation
\ne. Evaporation<\/p>\n

Question 3.
\nWhich of the following statements are \u201ctrue\u201d?
\na. Only during the monsoon season, the water vapour is present in the air.
\nb. Water vapourises into steam only from oceans, lakes and rivers but not from the soil.
\nc. The process of converting water into its vapour is called evaporation.
\nd. The process of evaporation takes place only in sunlight.
\ne. The water vapour condenses to form tiny droplets of water in the upper layers of air where it is cooler.
\nAnswer:
\na. False
\nb. False
\nc. True
\nd. False
\ne. True<\/p>\n

Question 4.
\nSuppose you want to dry your school uniform quickly. Would spreading it near an angithi or heater help? If yes, how?
\nAnswer:
\nYes, in order to dry the uniform faster, the uniform is spread near a heater since the rate of evaporation is faster at higher temperatures. The rate of evaporation is directly proportional to temperature. So, the uniform will be dried up quickly.<\/p>\n

Question 5.
\nTake out a cooled bottle of water from refrigerator and place it on a table. After some time, you will notice a puddle of water around the bottle on the table. Why?
\nAnswer:
\nSince the water bottle is at a very low temperature, the surface exposed is also very cold. As the cool surface is exposed, condensation of water vapour present in the air occurs. Now, the condensed water molecules spread around the bottle. So a puddle of water is noticed after some time.<\/p>\n

Question 6.
\nTo clean our spectacles, we often breathe out hot air on glasses to make them wet. Explain why the glasses become wet?
\nAnswer:
\nThe air we blow out contains water vapour. The water vapour condenses on the spectacles forming moisture and the glass is coated with a layer of minute water droplets. With the addition of small amount of water, we can easily clean the spectacles.<\/p>\n

Question 7.
\nHow are clouds formed?
\nAnswer:
\nThe water present on the earth\u2019s surface evaporates due to heat radiated by the sun. The water vapour present in the air condenses to form tiny droplets of water at high altitudes which in large quantity looks as clouds. Thus, clouds are formed by the condensation of water vapours available in the air at high altitudes.<\/p>\n

Question 8.
\nWhen does a drought occur?
\nAnswer:
\nWhen there is no rainfall for many years over a long period of time then there will arise a scarcity of water in that locality or region. This leads to drought.<\/p>\n

NCERT Extended Learning Activities and Projects<\/span><\/p>\n

Question 1.
\nList three activities in which you can save water. For each activity describe how you would do it.
\nHint:
\nWe can save water by rainwater harvesting, using pre-used water for watering plants and preventing water pollution in rivers, lakes, etc.<\/p>\n

Question 2.
\nCollect pictures relating to floods or droughts from old magazines or newspapers. Paste them in your notebook and write about the problems that people would have faced.
\nHint:
\nDo it yourself.<\/p>\n

Question 3.
\nPrepare a poster on ways of saving water and display it on your school notice board.
\nHint:
\nDo it yourself.<\/p>\n

Question 4.
\nWrite a few slogans of your own on the topic \u2018Save Water\u2019.
\nHint:
\nDo it yourself.<\/p>\n

Question 5.
\nCan the interlinking of rivers be a solution for mitigation of flood? Discuss.
\nHint:
\nYes, it can help in mitigation of flood as the excess water will distribute over a larger area leading to better maintenance of water levels during heavy rainfalls.<\/p>\n
