What are the components of air and their uses?

Answer 1

Air is mainly composed of nitrogen, oxygen, and argon, which together constitute the major gases of the atmosphere. The remaining gases are often referred to as trace gases, among which are the greenhouse gases such as water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Filtered air includes trace amounts of many other chemical compounds. Many natural substances may be present in tiny amounts in an unfiltered air sample, including dust, pollen and spores, sea spray, and volcanic ash. Various industrialpollutants also may be present, such as chlorine (elementary or in compounds), fluorine compounds, elemental Mercury, and sulfurcompounds such as sulfur dioxide [SO2].

Air also suspends clouds, which are water and turn into rain. This means that water moves around a lot. If water just sat around, a lot of things could only grow in a river.

Air also suspends objects. Think of it as swimming in water - just harder, so hard that it takes a bunch of smart people to figure out just how. Planes "float" on air.

Air holds heat, too. If there was no air, night would be colder than that stuff the doctor uses to freeze off your warts. All that energy from the sun would just leave instead of being held in by the air.

Air can also be a problem, it is hard for things to move around in it and it can push things. When you are walking around your living room this is not noticeable, but when you are driving a car really fast and watching that gas tank empty (or being impaled by flying debris in a hurricane) the "push" of air becomes a lot more noticeable.

In conclusion, air keeps things alive and powers the planet (and wastes your gas money, and kills people). Happy breathing!
