what is the 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..

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%), ..

Close the end of the tube at B. Keep your mouth at C, and suck in a breath of air. The air from the atmosphere enters through A, passes through the limewater, and comes into your mo..

Air Pollution - The major problem that the atmosphere is being subjected to is pollution. In India, about 100 million tons of pollutants are being added to the atmosphere annually. This figure is likely to go up in future. Polluted air is harmful to man and the biosphere on the ..

Butane with small quantities of ethane and propane. These gases can be liquified under pressure and bottled in cylinders. By itself LPG is odourless. On leakage, it is toxic if inhaled. It also forms an explosive mixture with air. LPG can be hazardous if handled carelessly. A strong smel..

It is an inexhaustible natural resource. It is very essential for the survival of all the living organisms on earth. In atmosphere, about 95% of the total air is present upto a height of 20 km above the earth's surface. The remaining 5% of air is present up to a height of ..

Air mainly consists of nitrogen and oxygen. Oxygen and nitrogen gases can be obtained separately by fractional distillation of liquefied air. Nitrogen distils over as vapour at a lesser boiling point (at 77.3 K) and liquid oxygen (at 90 K) is left behind in the fractionating co..
