NCERT Solutions for Class 6 Science Chapter 14 Water: Exercise Solutions

Q. 1. Fill up the blanks in the following:

Answer: (a) The process of changing of water into its vapour is called evaporation

(b) The process of changing water vapour into water is called condensation

(c) No rainfall for a year or more may lead to drought in that region.

(d) Excessive rains may cause floods.

Q. 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 water
(b) Steam rising from wet clothes while they are ironed
(c) Fog appearing on a cold winter morning
(d) Blackboard dries up after wiping it
(e) Steam rising from a hot girdle when water is sprinkled on it

Answer: (a) Water drops appear on the outer surface of a glass containing cold water. $\rightarrow$ Condensation

(b) Steam rising from wet clothes while they are ironed. $\rightarrow$ Evaporation

(c) Fog appearing on a cold winter morning. $\rightarrow$ Condensation

(d) Blackboard dries up after wiping it. $\rightarrow$ Evaporation

(e) Steam rising from a hot girdle when water is sprinkled on it. $\rightarrow$ Evaporation

Q. 3. Which of the following statements are “true”?

Answer: (a) Water vapour is present in the air only during the monsoon. FALSE

Correct:- There is always a small amount of water vapour present in the air.

(b) Water evaporates into the air from oceans, rivers and lakes but not from the soil. FALSE
Correct:-
Water also evaporates from the soil.

(c) The process of water changing into its vapour is called evaporation. TRUE

(d) The evaporation of water takes place only in sunlight. TRUE

(e) Water vapour condenses to form tiny droplets of water in the upper layers of air where it is cooler. TRUE

Answer: Yes, I will spread it near an angithi or heater, because the heat generated from an angithi or a heater causes the water to evaporate at a faster rate. Therefore, helps in drying the clothes quicker rate.

Answer: This will happen because when we take a water bottle out of the refrigerator, the surface of the water bottle is cold which cools the surrounding air and because of condensation water vapour in the air condenses around the surface of the bottle and form droplets of water around it.

Answer: Because as the breath that is coming out of the mouth is moist, thereby making the glass of spectacles cooler. And because of that, water vapours that are present in the air surrounding the glass condense and get attached to the glass surface. Therefore, the glass becomes wet.

Answer: We know that clouds are formed by the process of condensation and evaporation. When water from the oceans, ponds, rivers, lakes, plants, fields, and other land surfaces evaporates, warm and moist air rises in the atmosphere. At higher altitudes, when the air becomes cooler and water vapour contained in the air condenses. On condensation, these form tiny water droplets. These tiny water droplets collect and float in the air as clouds.

Answer: When there is no rain for one or two years then chances of drought occurs. Because usually, due to evaporation and transpiration water is lost by soil, pods, lakes etc. But if no rainfall will occur for a longer period of time, then the water level in various ponds, river, lakes and wells decreases. This leads to the condition of drought.
