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 definite volume. When any of ..

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 handled carel..

The credit of discovery of first noble gas argon goes to Henry Cavendish who performed number of experiments to study the composition of air. He found that air is approximately 79 per cent nitrogen and 21 per cent oxygen by volume. Traces of carbon dioxide and water vapor were ..

Gaseous Exchange - Exchange of Respiratory Gases The exchange of respiratory gases is through membranes. In lungs, the gases are exchanged between the lungs and the blood capillaries and in the tissues, the gases are exchanged between the cells and the blood surrounding them. The gases move across ..

The nitrogenous waste materials produced in the animal body due to metabolic reactions are of no use to the cell. These waste materials if allowed to accumulate in the body, may become toxic. Therefore, they must be removed from the body. The process of elimination of metabolic waster products from..

Chemical Change - A change in which the composition of a substance is altered is called as chemical change. As a result, the original properties get changed and one or more new substances are formed. Iron is greyish white metal and conducts electricity. It is attracted by a magnet, and re..
