Question

1. Name all the gases present in the air
2. Define Humidity
3. Explain how water vapour are formed in the air
4. Write three uses of air,
5. Name different layers of atmosphere.
6. Describe briefly about the composition of air and its constituent use
7. With the help of diagram, explain the process of distillation of water​

Answer 1

Answer:

1)Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases. The atmosphere also includes water vapor.

2.a quantity representing the amount of water vapour in the atmosphere or in a gas.

3.Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation.

4.Important Uses of Air

Sustain life and growth.

Combustion.

Maintaining Temperature.

Supplier of Energy.

Photosynthesis.

5.The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.

Answer 2

1) The gases present in our atmosphere are oxygen,Carbon dioxide,Nitrogen ,SulpherDioxide,etc

2) The amount of Water vapour present in air is called humidity

3) Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation.

4)Sustain life and growth.

5) The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.

6) 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.
