Air is an invisible gaseous material that surrounds the earth and is primarily composed of oxygen and nitrogen.

Atmosphere refers to the blanket of air that surrounds the world.
Air can be found in all places. Although we cannot see air, we can feel it.
The wind is the movement of air.
Air takes up space and is found in water and dirt.
Nitrogen, oxygen, carbon dioxide, water vapour, and a few more gases make up air. It may also contain some dust particles.
Life on Earth depends on the atmosphere.
Aquatic species breathe dissolved air in water, and plants and animals rely on each other for oxygen and carbon dioxide exchange from the air.

Different Layers of Atmosphere:

Troposphere
Stratosphere
Mesosphere
Thermosphere

Constituent of Air:

The main components of air are nitrogen and oxygen. Nitrogen makes up about 78 per cent of the air we breathe. Nearly 21% of the air is made up of oxygen. Carbon dioxide, water vapour, dust particles, and other gases make up the remaining 1%. The composition of gases in the air varies by location.

Nitrogen: Plants require nitrogen in order to grow.
Oxygen: All living things use oxygen to breathe and to help them burn food.
Carbon Dioxide: During respiration, plants and animals absorb oxygen and create carbon dioxide. Photosynthesis is carried out by green plants. It is emitted when you burn something.
Water Vapour: Water vapour is formed when water evaporates. Humidity refers to the amount of water vapour in the air. Variates from place to place, as well as during the day and night in the same location.
Dust and Smoke: Smoke comprises a small number of gases as well as fine dust particles. It is really dangerous. The number of dust particles in the air changes throughout time and from location to place.

Importance of Air:

Burning is aided by the presence of air.
Breathing necessitates the presence of air.
Plants require air to produce food.
Birds fly across the air. Air pressure also causes planes to rise in the air.
The wind is the term for moving air. The windmill rotates because of the wind.
Air helps in the rapid evaporation of sweat, which keeps us cool.

FAQs on Air Around Us Class 6 Notes CBSE Science Chapter 11 (Free PDF Download)

1. What is air made up of according to Class 6 Science Chapter 11 Air Around Us?

The majority of naturally occurring gases, or around 78% of air, are composed of nitrogen. The second most prevalent gas in the atmosphere is oxygen, which has a prevalence of about 21%. An inert gas called argon makes about 0.93% of the entire makeup. Carbon dioxide, neon, helium, methane, krypton, hydrogen, nitrous oxide, xenon, ozone, iodine, carbon monoxide, water vapours, and ammonia are all present in trace levels in the atmosphere.

2. How will you prove that air supports burning with reference to Chapter 11 of Class 6?

We can demonstrate that burning occurs in the air by performing the following experiment:

Put two candles on a table that are already burning. Now, place a glass tumbler on top of one candle to cover it.

You'll observe that although the other candle keeps burning, the candle covered by the inverted glass tumbler eventually goes out. The absence of air inside the glass tumbler is the reason for this. However, the air that was initially in the glass tumbler gets burned away. This demonstrates that burning occurs in the air. You can refer to other Air Around Us Notes on Vedantu for Class 6.

3. Does air have weight according to Class 6 Science Chapter 11 Air Around Us?

Since we are aware that air is a substance, it must be heavy. By weighing an inflated balloon and comparing its weight to the weight gained when it is not inflated, you may determine it. A balloon that has been inflated will weigh more than one that has not. We can refer to more questions related to air on Vedantu and their notes related to the same.

4. What are the 6 uses of air according to Class 6 Science Chapter 11 Air Around Us?

Natural resources like air are widely available. The first thing we can say when discussing the uses of air is that it is the most crucial component for maintaining the health and vigour of all life on earth. Having said that, the air is extremely beneficial and has many uses, much like water, including supporting life and growth, combustion, maintaining temperature, supplying energy, photosynthesis, etc.

5. Can we see air yes or no?

We have evolved retinas that are sensitive to the same wavelengths of light that flow through the air without being impeded; otherwise, we wouldn't be able to see anything at all. This is why air appears transparent to our eyes. Air is simply in motion, and pressure changes in the atmosphere are what generate wind.
