It surrounds us during our entire lives, and we breathe it in and out from our first to our last moment. Without it, there would be no life on our planet. We are talking about one of the four elements, air. The air combines gases that make up the earth’s atmosphere. Dry air is mainly composed of two gases: Nitrogen (N2) is the primary air component at 78.08 percent. At 20.92 percent, oxygen (O2) is the second most crucial component.
Furthermore, air contains noble gases (0.93 percent in total), mainly argon, as well as helium, neon, krypton and xenon. In addition, carbon dioxide (CO2) makes up 0.037 percent, and is one of the main air components due to its importance for living organisms and the climate. The air also includes methane, hydrogen, nitrous oxide (laughing gas) and carbon monoxide. In this article of Gazettely, we will tell you nine interesting things about the air that you probably don’t know.
We have studied them for years, but lightning still hides many mysteries. For example, we have no evidence that, in the clouds, ice particles and “round snow” are the ones that transmit the electric charge to the air. And more importantly: despite decades of studies with probes, the electrical field that would be necessary to trigger them has never been recorded. In fact, the calculated one theoretically turns out to be ten times more intense than the one actually measured.
