29 Apr Air and its properties
Many students of Singapore after facing difficulties to understand the concepts of Chemistry came to Miracle Learning Centre for help. Our students have hailed us as the best chemistry tuition of Singapore. This is simply because after enrolling in our A Level Chemistry, O Level Chemistry and JC Chemistry classes, students of Singapore have found that our teachers are the nicest person and they teach the most difficult topics by introducing students to various games and activities which while giving them a new age learning experience also helped them to score more. Below is an example of a Chemistry lesson of our tuition class.
The Earth’s atmosphere is Air, it is a mixture of many gases and dust particles and supports life by helping us to breathe. Air is colour and odourless and is without any indefinite shape and volume. Air is a matter and so it has mass and weight.
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.
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 chemistry tuition questions. Do come to Miracle Learning Centre for more chemistry tuition lessons to learn more about air and its properties and chemistry.
