CHAPTER 14_WATER NCERT SOLUTIONS
1. Fill up the blanks in the following :
a) The process of changing of water into its vapour is called_________________.
b) The process of changing water vapour into water is called_________________.
c) No rainfall for a year or more may lead to _________________ in that region.
d) Excessive rains may cause_________________.
A. a) evaporation b) condensation c) drought d) floods
2. State for each of the following whether it is due to evaporation or condensation :
a) Water drops appear on the outer surface of a glass containing cold. Condensation
b) Steam rising from wet clothes while they are ironed. Evaporation
c) Fog appearing on a cold winter morning. Condensation
d) Blackboard dries up after wiping it. Evaporation
e) Steam rising from a hot girdle when water is sprinkled on it. Evaporation
3. Which of the following statements are “True”?
a) Water vapour is present in air only during the monsoon. ( F )
b) Water evaporates into air from oceans, rivers and lakes but not from the soil. ( F )
c) The process of water changing into its vapour, is called evaporation. ( T )
d) The evaporation of water takes place only in sunlight. ( F )
e) Water vapour condenses to form tiny droplets of water in the upper layers of the air where it is cooler. ( T )
4. Suppose you want to dry your school uniform quickly. Would spread it near an anghitior heater help? If yes, how?
A. Yes,
i) Spreading uniform near anghitior heater will help in drying.
ii) The temperature near anghitior heater is much higher when compared to surroundings.
iii) Hence, the process of evaporation of water is faster. This will lead to quick drying of uniform.
5. Take out a cooled bottle of water from refrigerator and keep it on a table. After sometime, you notice a puddle of water around it. Why?
A. i) We know that water vapour is present in atmosphere.
ii) When a cooled bottle is kept on a table, the water vapour in atmosphere comes in contact with the cooler surface of bottle and gets condensed.
iii) The water drops are formed and are accumulated on the table around the bottle. Hence, we can notice a puddle of water around it.
6. To clean their spectacles, people often breathe out on glasses to make them wet. Explain why the glasses become wet ?
A. i) When we breathe out, water vapour comes out with exhaled air.
ii) This water vapour when comes in contact with the glasses of spectacle, makes them wet.
7. How are clouds formed?
A. i) Water evaporates continuously from the surface of water bodies like seas, oceans, rivers, ponds, etc., and changes into water vapour due to the heat supplied by sunlight.
ii) Water vapour at high altitudes condenses due to contact with cool air and forms small water droplets.
iii) These tiny droplets of water float in air at higher levels and form clouds.
8. When does a drought occur?
A. A drought occurs when there is scanty rainfall or no rain for a very long time.
