FAQs on CBSE Class 6 Science Air Around Us Worksheets
1. Important uses of Air?
Air is one of the natural elements present on Earth. Air consists of mainly three types of gases on Earth; 78% Nitrogen, 21% Oxygen and the remaining 2% of other gases.
Air is useful in several ways in our daily lives. As humans, air (oxygen) is transported throughout our body, down to every cell via our bloodstream. This allows our body to undergo digestion and respiration. Plants use air (carbon dioxide during the day and oxygen at night) as well to create their food by Photosynthesis.
On the commercial side of things, the air is used for filling vehicle tyres, hot air balloons and footballs.
2. What are the properties of air?
The air can be described as having the following properties:
Air is not visible and is colourless in nature.
Air movement can be felt and fast-moving air is called wind.
Air is present in all places. It not only occupies but also is dissolved in water.
Air can also be stored in containers and is compressible. It even exerts pressure when stored.
Air is consumed by all living beings, animals and organisms.
Air is an essential element and it helps to sustain life on earth. It surrounds the earth in the form of the atmosphere.
3. How will you prove that air occupies space?
One can prove that air occupies space through a simple test.
Take a bucket, some water and an empty bottle. Fill the bucket with water. Grab the empty bottle from before (can be plastic or any other material) and try to push it downwards in the filled bucket. Resistance can be felt during this process.
Next, start tilting the bottle upside down and note the observations. When the bottle was pushed directly downwards, no water entered the bottle, while the bottle was tilted air bubbles could've been seen allowing water to enter the bottle, proving that air occupied the space in the bottle.
4. Can it be proved that air is dissolved in water?
To prove that air is dissolved in water, you can perform a small experiment. All you need to do is take a beaker filled with water. Then heat the beaker slowly for some time. After a few minutes, there will be bubbles forming inside the beaker. These bubbles on the inner surface of the beaker indicate the presence of air inside the water. Thus, it proves that air is dissolved in water. It also showcases how air is indeed present in all places.
