Chemistry tuition classes in Miracle Learning Centre is very useful. If you do not understand chemistry, you must definitely attend the chemistry tuition class at Miracle Learning Centre. Let us learn about air and its properties in this chemistry tuition lesson. Your chemistry tuition teacher at Miracle Learning Centre will teach you about air and its properties. Air supports life. Processes such as photosynthesis, combustion and respiration, all require air. Air is a mixture of gases. It is made up of 78% nitrogen, 21% oxygen, 1% noble gases, 0.03% carbon dioxide and water vapour. Since air is a mixture, the composition of air varies from place to place. The amount of water vapour in the air also varies. On a humid day, there is a lot of water vapour in the air, hence, we perspire more easily.

Your chemistry tuition teacher at Miracle Learning Centre will teach you about air and its properties. Air supports
life. Processes such as photosynthesis, combustion and respiration, all require air. Air is a mixture of gases. It is made
up of 78% nitrogen, 21% oxygen, 1% noble gases, 0.03% carbon dioxide and water vapour. Since air is a mixture, the
composition of air varies from place to place. The amount of water vapour in the air also varies. On a humid day,
there is a lot of water vapour in the air, hence, we perspire more easily.
Nitrogen is a colourless, odourless gas, and is the most abundant gas in the air. Nitrogen is less dense than air.
Oxygen is also colourless and odourless, similar to nitrogen. However, it has approximately the same density as air.
The student at Miracle Learning Centre asked, "Why is nitrogen the most abundant gas instead of oxygen?"
The chemistry tuition teacher at Miracle Learning Centre replied, " Nitrogen is an inert and does not combine easily
with other substances as compared to oxygen which is very active as it readily combines chemically with many
substances to form other new substances."
Miracle Learning Centre hope you have understood the air and its properties and how it helps you to answer
