NCERT Solutions for Class 6 Science Chapter 11 - Air Around Us

1. What is the Composition of Air?

Ans:

• Air is surrounded everywhere which is a mixture of different gases and dust particles. 

• The composition of different gases present in the air includes nitrogen (78%), oxygen (21%), and other gases along with dust particles (1%).

2. Which Gas in the Atmosphere is Essential for Respiration?

Ans: For respiration, oxygen gas present in the atmosphere is essential.

3. How Will You Prove that Air Supports Burning?

Ans:

• Air support burning can be proved by an experiment. 

• In this experiment, a burning candle is placed in the utensil filled with water and the neck of the candle is not submerged in the water.

• After that, keep an inverted glass over the candle.

• As a result, the candle is extinguished and the water level is raised due to oxygen consumed by the burning candle.

• This proves that air supports combustion.

4. How Will You Show that Air is Dissolved in Water?

Ans: 

• Air dissolved in water can be shown by an experiment.

• Take a glass filled with water.

• Heat the water present in the glass.

• You can see the bubbles coming out.

• The bubbles are formed before the water reaches its boiling point.

• This indicates air is dissolved in water.

5. Why Does a Lump of Cotton Wool Shrink in Water?

Ans: 

• The lump of the cotton wool shrinks in water because the water occupies the air present in the cotton. 

• As a result, the volume of the cotton and cotton shrink.

6. The Layer of Air Around the Earth is Known as_____.

Ans: atmosphere

7. The Component of Air Used by Green Plants to Make Their Food is ______.

Ans: carbon dioxide

8. List Five Activities that are Possible Due to the Presence of Air.

Ans: The five activities that are possible due to the presence of air are:

i. Photosynthesis

ii. Transpiration

iii. Respiration

iv. Winnowing

vi. Cloud formation

9. How Do Plants and Animals Help Each Other in Exchange of Gases in the Atmosphere?

Ans: 

• Animals inhale oxygen and release carbon dioxide into the atmosphere. 

• The carbon dioxide is taken by the plants to prepare their food by the process of photosynthesis and releases oxygen.

• The oxygen is then again taken by the animals to breathe.

• In this way, plants and animals help each other in exchange of gases.
