atmospheric co2 levels

The gaseous envelope surrounding the Earth is called earth's atmosphere, extending to a few kilometres above the surface. The pressure exerted by the atmosphere is called atmospheric pressure. The magnitude of this pressure is nearly 1.01x10 5 N/m 2 (Refer ..

The atmosphere is the layer of air around the earth. It extends up to 1000 km above the surface of the earth and has a total weight of 4.5 10 1 8 kg (i.e., five million billion tons). This weight exerts a pressure on the surface of the earth which is called atmospheric press..

The maximum height of mercury, which can be supported by the atmospheric pressure provides a measure of that pressure. A standard pressure of one atmosphere (1 atm) is defined as the pressure that will support a column of mercury of 76 cm height at 0C (density of mercury (13.59..

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 the ..

The air we breathe, the water we drink, stones and rocks, almost everything that is around us, are all useful to man for some purpos..

Greenhouse Effect - The Greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (referred to as greenhouse gases), trap energy from the Sun. Without these gases heat would escape back into space and living on Earth would be inhospita..

Pollution Due to the Burning of Fossil Fuels (Additional) - Contamination of air with harmful toxic gases, smoke and particulate matter (e.g., dust etc.) is called air pollution. The substances that cause pollution are called pollutants. Combustion of fossil fuels is one of the main causes of pollu..

. It is manufactured by the Ostwald's Process by the reaction of ammonia and air in presence of platinum as catalyst at 700-800 o C. Nitric acid is colourless in pure form. Commercial nitric acid is yellowish due to the presence of dissolved nitrogen dioxide. Basic oxide + nitri..
