Question

Write some uses of following :

• Oxygen
• Nitrogen
• Carbon dioxide
• Water vapour
• Inert gases

Answer 1

Uses of Oxygen (O₂) are as follows:

• Oxygen is the lifeline of all living organisms.
• It helps in burning.
• It is used in hospitals to support life of those patients who are not able to take breaths properly.
• Compressed oxygen tanks are used by mountaineers.
• It is also used in the production of many things like textile, and other chemicals.

Uses of Nitrogen (N) are as follows:

• Nitrogen is used to give the unreactive atmosphere.
• Living organisms require nitrogen for protein formation.
• Nitrogen is used in the manufacturing of many chemicals in industries.

The uses of Carbon dioxide (CO₂) are as follows:

• Carbon dioxide is important for the photosynthesis process(preparation of food by plants).
• It is also required in the atmosphere to maintain the earth's temperature normal for living organisms.
• It maintains the pH level of a human being.

The uses of Water vapour are as follows:

• Presence of water vapour in the atmosphere is very important for water cycling in the atmosphere.
• water vapour determines the climatic condition of the area.
• It also determines the rate of transpiration and evaporation in the atmosphere.

The uses of inert gases are as follows:

• Inert gas helium is used in weather observation balloons.
• Inert gas argon is used in bulbs to prevent oxidation of the filament of the bulb.
• Neon is used in advertisement boards to glow in the night.
