Components of Air
The atmosphere of the Earth contains roughly 78 percent nitrogen and 21% oxygen. There are also trace quantities of several other gases in the air, including carbon dioxide, neon, and hydrogen. The molecules of many gases make up the air in our environment. The most prevalent gases are nitrogen (78%), oxygen (approximately 21%), and argon (about 2%). (almost 1 percent). Other molecules can also be found in the atmosphere, although in extremely tiny amounts.
- Oxygen – Oxygen and air are frequently used interchangeably, although they are not the same substance. Air, on the other hand, is a combination of many elements, whereas oxygen is a pure element. The earth’s major component, air, has a healthy mix of components that aid in the survival of human existence.
- Nitrogen – Nitrogen makes up 78% of the air we breathe, and the majority of it is considered to have been trapped in the primordial debris that created the Earth. They solidified when they collided, and their nitrogen content has been leaking out of the planet’s crust’s molten fissures ever since.
- Argon – When an inert atmosphere is required, argon is frequently utilized. It is utilized in the synthesis of titanium and other reactive elements in this way. Welders use it to shield the weld area, and incandescent light bulbs use it to keep the filament from corroding due to oxygen.
- Carbon dioxide – Atmospheric carbon dioxide level was 409.8 parts per million, with a margin of error of 0.1 ppm. Carbon dioxide levels are now greater than they have been in at least 800,000 years.
- Water vapour – Absolute humidity refers to the quantity of water vapour in the air. Relative humidity refers to the quantity of water vapour in the air compared to the amount of water that the air can contain.
