NCERT Solutions Class 6 Chapter 15 – A Brief Explanation 

Chapter 15 – Air Around Us Class 6 is focused on air, its composition, and how crucial  it is for life. One of the most important topics covered in this chapter is the composition of  air. Earlier people used to think that air is just a single substance. However, later studies showed that Air is in fact a mixture of many different gases. These majorly include:

  • Water vapor
  • Oxygen
  • Nitrogen
  • Carbon dioxide
  • Dust and  smoke

The chapter highlights the uses and properties of all these constituents of air. Later students also learn in this chapter how the oxygen in the air is made available to animals and plants living in  water and soil. Students will learn that oxygen gets dissolved in water which is used by animals and plants living  in water. Similarly, the air gets trapped between burrows in soil which is used by animals living in  the soil to respire.

Q.1 What is the composition of air?

Air is a mixture of nitrogen, oxygen, small amount of carbon dioxide, water vapour and some other gases. Nitrogen constitutes 78% of the air. Oxygen constitutes 21% of the air. Carbon dioxide, water vapour and other gases constitute only 1% of the air.

Q.2 Which gas in the atmosphere is essential for respiration?

Oxygen is essential for respiration.

Q.3 How will you prove that air supports burning?

To prove that air supports burning, we will perform an activity.

To perform this activity, things required are candle, water, container and matchbox.

First of all take a container and fix a candle in the middle of the container. Fill the container with some water. Now, light the candle and then cover it with an inverted container.

After some time, it is observed that candle extinguishes.

Candle extinguishes because the amount of air is limited inside the inverted container. Hence, supply of oxygen is also limited.

Once oxygen is completely consumed, the candle blows off. This proves that oxygen is essential for burning.

Q.4 How will you show that air is dissolved in water?

To show that air is dissolved in water, take some water in a pan and heat it slowly. Just before the water begins to boil, look carefully at the bottom of the pan. Tiny air bubbles are seen at the bottom of the pan before the water actually boils. These air bubbles come from the air dissolved in water. When we heat the water, air dissolved in it escapes.

Q.5 Why does a lump of cotton wool shrink in water?

A lump of cotton wool shrinks in water because when it is immersed in water, air present in it escapes and it reduces in size.

Q.6 The layer of air around the earth is known as ______.

The layer of air around the earth is known as atmosphere.

Q.7 The component of air used by green plants to make their food, is ___________.

The component of air used by green plants to make their food, is carbon dioxide.

Q.8 List five activities that are possible due to the presence of air.

Activities that are possible due to the presence of air are:

  1. Photosynthesis
  2. Respiration
  3. Flight of birds, bats and insects
  4. Movement of sailing yachts, gliders, parachutes and aeroplanes
  5. Generation of electricity by windmill

Q.9 How do plants and animals help each other in the exchange of gases in the atmosphere?

During photosynthesis plants take carbon dioxide from atmosphere and make their own food and oxygen is produced in this process. Plants also consume oxygen during respiration but amount of oxygen released during photosynthesis is more than the amount of oxygen used during respiration. Animals inhale oxygen produced by plants and in turn, carbon dioxide is produced.

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

3. Explain with a simple experiment that air supports burning.

In this experiment,  you need to light a pair of candles. Next,  cover one of these candles with an inverted glass. The covered candle extinguishes after some time. The uncovered candle stays lit. This is because there is no supply of air in the covered candle- so the light extinguishes while the uncovered candle gets the air required to let the candle burn is actually supported by the oxygen present in the air. . This proves that air supports burning and oxygen is the component of air that supports it. .


4. What is wind according to Chapter 15 of Class 6 Science?

When the air is moving it is called wind. This moving air has direction and speed and it can be felt as well. The movement of sand and the falling of leaves occurs because of the speed of the wind. The direction of raindrops and the movement of clouds across the sky are a few other examples of the influence of wind. The three types of wind are:

  • Permanent Wind: This wind blows only in one direction throughout the year.
  • Seasonal Wind: These winds change as per change in seasons.
  • Local Wind: These types of winds blow during a particular period of a day or year. The movement of these winds is usually in small areas.
