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..

Composition of LPG - 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 han..

Gas Behaviour - All gases, irrespective of their chemical composition, obey certain laws that govern the relationship between the volume, temperature and pressure of the gases. A given mass of a gas, under definite conditions of temperature and pressure, occupies a def..

It is a mixture of gaseous hydro-carbons. It is found usually along with petroleum deposits. Natural gas consists mainly of 85% methane, 10% of ethane and 3% of propane and butane. It may also contain nitrogen, oxygen, carbon di-oxide and hydrogen sulphide. Its great advantage is that it ..

Air is an important natural resource providing the basis of life on earth. Entire biosphere depends on air. Air in the atmosphere provides oxygen to plants and animals, by virtue of which they are able to live. The composition of air (78% N, 21% O, ..

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 ..
