Exercise Question

Question 1

Fill up the blanks in the following:
(a) The process of changing of water into its vapor is called _________________.
(b) The process of changing water vapor into water is called _________________.
(c) No rainfall for a year or more may lead to _________________ in that region.
(d) Excessive rains may cause _________________.

Answer 1

(a) The process of changing of water into its vapor is called evaporation .
(b) The process of changing water vapor 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.

Question 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 2

Question 2

Which of the following statements are “true” ?
(a) Water vapor is present in air only during the monsoon. ( )
(b) Water evaporates into air from oceans, rivers and lakes but not from the soil.( )
(c) The process of water changing into its vapor, is called evaporation.( )
(d) The evaporation of water takes place only in sunlight.( )
(e) Water vapor condenses to form tiny droplets of water in the upper layers of air where it is cooler.( )

Answer 3

Question 4

Suppose you want to dry your school uniform quickly. Would spreading it near an anghiti or heater help? If yes, how?

Answer 4

As we know rate of evaporation increase with increase of temperature So Spreading uniform near an anghiti or heater will help because it increases the rate of evaporation due to heat.

Question 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?

Answer 5

it is due to condensation of water ,As air around the surface of bottle lose temperature and convert into water droplets by the process of condensation.

Question 6

To clean their spectacles, people often breathe out on glasses to make them wet. Explain why the glasses become wet.

Answer 6

As we breath out air coming out from mouth cool down on the surface of glass hence glass becomes wet.

Question 7

How are clouds formed?

Answer 7

s Clouds are formed by the process of evaporation and condensation.The process of condensation plays an important role in bringing water back to the surface of the earth. At a certain height from the surface of the earth, it gets cooler. When the air moves up, it gets cooler and air becomes so cool that the water vapor present in it condenses to form tiny drops of water called droplets. It is these tiny droplets that remain floating in the air and appear to us like clouds.

Question 8

When does a drought occur?

Answer 8

If it does not rain for two or more years in region . the soil lose water continues due to evaporation and transpiration. This cause soil and the water in the ponds and lakes are dried up,and this situation leading to drought condition
