Composition of Air
Composition of Air - For thousands of years, air was considered to be a mixture of many gases. The true composition of air was not known for a long time. Air is a mixture of various gases. The main gases present in air are nitrog..
Composition of Air
Air is a mixture of various gases. The main gases present in air are nitrogen (78.1% by volume) and oxygen (20.9% by volume). These two gases together form 99% of the air. Besides these two, air contains small amounts of carbon dioxide (0.03 to 0.04%), ..
Pie Graph or Pie Chart
Sometimes a circle is used to represent a given data. The various parts of it are proportionally represented by sectors of the circle. Then the graph is called a Pie Graph or Pie Cha..
Air
Air around earth is not uniform throughout the atmosphere. The density of air is gradually reduced with altitude. Although atmosphere is spread to 200 km around earth, the oxygen content beyond 5 km above surface of earth hardly supports any life. The composition of h..
Composition of atmospheric air
. This zone is called troposphere. Therefore, at higher altitudes, some of us find it difficult to breathe. Above the troposphere is the stratosphere. This zone is rich in ozone. Hence, it is also called ozonosphere. In ozonosphere, the sunlight converts oxygen to ozone by photochemical dissolution..
