What are the uses of air short answer?

Air consists one of the main life-sustaining gas called oxygen. Almost all living things breathe in and breathe out this air. Nitrogen and Carbon dioxide are also other gases that are vital for plants and their growth.

Where this property of air is useful?

Answer: Photosynthesis. Carbon dioxide which is also a component of air is used by plants during the process of photosynthesis and oxygen, water vapor is released by plants as a by-product. Apart from these gases, other gases are also useful such as nitrogen is used in the production of ammonia.

Which of the following is a use of air?

Which is not properties of air?

(d) it is a compound is not the property of air. Air is a combination of gases and hence it is a mixture. Compound is characterized by chemical bonding between the elements. Mixture is formed by physical mixing of elements which is seen in air.

What is air write composition?

The Composition of Air:

Air is made up of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and other gases in meager amounts. Water vapor is also a constituent of air in varying amounts along with dust particles. The molar mass of dry air or air with no/low quantity of water vapor in it is 28.97g/mol.

Which is not property of air Class 6?

Answer: (d) It is a compound. Explanation: Air is a homogeneous solution, which occupies space and it is transparent. So air is not a compound.

What is air made up of Class 6?

Answer: Air is a mixture of 79% nitrogen, 20% oxygen, 1% carbon dioxide, water vapours and some other gases. Air also contains dust particles.

What is air made up of Class 6 science?

Answer: Air is a mixture of 79% nitrogen, 20% oxygen, 1% carbon dioxide, water vapours and some other gases. Air also contains dust particles.

What are the properties of air pressure?

It has mass. It exerts some space. It exerts pressure since the weight of air denotes the atmospheric pressure. It is also considered as a matter.

How do you show the weight of air?

In the balloon balance experiment, we are blowing up balloons. When blow-up balloons, the air is entering inside them and making the balloons expand. So, this shows that the air occupies space which eventually proves that it has weight.

How do you describe air?

Air is a mixture of many gases and tiny dust particles. It is the clear gas in which living things live and breathe. It has an indefinite shape and volume. It has mass and weight, because it is matter.

How do you show air pressure?

Wrap a lump of clay around the straw to form a seal. Blow hard into the straw—then stand back. Your blowing increases the air pressure inside the sealed bottle. This higher pressure pushes on the water and forces it up and out the straw.

What is the properties of air in chemistry?

Air is a mixture of gases which makes up the Earth’s atmosphere. These gases are colorless and odorless and hence, we can’t see them but only feel them. The atmosphere is an ocean of these gases. It consists of 78% nitrogen, 21% oxygen and 1 % other gases and water vapour.

What is air and its use?

IAir contains oxygen that we breathe and protects us from the harmful UV rays of the sun. Air is a mixture of different gases and is all around us. Atmosphere consists mainly of nitrogen (78%), oxygen (21%), argon (0.93%), carbon dioxide (0.03%) and other gases like helium, ozone, argon and hydrogen (0.04%).

Why air is useful to us?

The air gives energy for the function of living things. Plants get their food from the event of Photosynthesis. Photosynthesis happens with the help of oxygen. Nitrogen is very useful for the growth of plants as well as trees.

What is one way we use the properties of air in our daily lives?

Air is important for the breathing of all living things on Earth. It provides oxidation processes that supply the body with the necessary energy. It is a significant supplier of energy: all living plants and animals depend on oxygen to generate valuable energy.

Where do we find air give examples?

Air is present everywhere around us and it is must requirement for all living beings. We must not have seen air but we always feel its presence around us. For example, when the leaves of the trees rustle or the clothes hanging on a clothes-line sway. Pages of an open book begin fluttering when the fan is switched on.

What is air used for as a natural resource?

The oxygen in the air is essential for animals to survive because we use this oxygen to produce energy from the food we eat. The carbon dioxide we breathe out is in turn required for plants to trap energy from the sun and turn it into food.

What are the properties of matter?

The properties of matter include any traits that can be measured, such as an object’s density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more.

What is the composition of air on Earth?
