Welcome to our Physics lesson on Air as a Mixture of Gases, this is the first lesson of our suite of physics lessons covering the topic of Gas Pressure, you can find links to the other lessons within this tutorial and access additional physics learning resources below this lesson.
Atmosphere - as the layer that surrounds the Earth - is composed by a mixture of gases, which we call "air". Atmosphere is made of 78% nitrogen (N2), 21% oxygen (O2) and 1% are other gases where the most important is carbon dioxide (CO2). Air is a fluid, and as such, it possesses all properties a fluid has, where one of the most important is the pressure it exerts on objects in contact.
Given this, we will explain air pressure first and then we will deal with other specific gases.
