Carbon monoxide is an extremely poisonous gas as a result of its physical properties, which add to the deadly nature of the gas. As the gas is almost odourless, its presence cannot be detected. Also its vapour density is almost equal to that of air. Hence it mixes easily with air. It neither goes ..

Earth is an abundant source of material. Man has intensively studied the properties of these materials extensively and found new methods of using them. The air we breathe, the water we drink, stones and rocks, almost everything that is around us, are all useful to man for some purpose or ..
