Awesome Facts About Oxygen
Oxygen, a chemical element we can’t live without. But what can happen if the world lost oxygen for 5 seconds? Or what if the amount of oxygen would doubled? Check out these awesome facts about oxygen.
1. Everyone at the beach would get sunburns
Ozone is molecular oxygen, and blocks the majority of UV light. It protects our skin.
2. The day-time sky would get darker.
With fewer particles in the atmosphere to scatter blue light, the sky would get a bit less blue and a bit more black.
3. All pieces of untreated metal would instantly spot weld to each other.
The reason metals don’t weld on contact is they are coated in a layer of oxidation. In vacuum conditions, metal welds without any intermediate liquid phase.
4. The Earth’s crust would crumble
Oxygen makes up 45% of the Earth’s crust
5. Everyone’s inner ear would explode.
We would lose about 21% of the air pressure in an instant (~ from sea level to 2000m elevation), so expect some serious hearing loss.
6. Every building made out of concrete would turn to dust.
Oxygen is an important binder in concrete structures (really, the CO2 is), and without it the compounds do not hold their rigidity.
7. The oceans would evaporate and bleed into space.
As oxygen disappears from the oceans’ water, the hydrogen component becomes an unbound free gas. Hydrogen gas, being the lightest, will rise to the upper troposphere and slowly bleed into space through Atmospheric escape.
8. Every internal combustion engine would stall.
This means that every airplane taking off from a runway would likely crash to the ground, while planes in flight could glide for some time.
9. Every living cell would explode in a haze of hydrogen gas.
Water is 88.8% oxygen; without it the hydrogen turns into gaseous state and expands in volume.
Now, what if amount of oxygen would doubled?
10. Paper airplanes would fly further.
11. We would get better gas mileage.
12. We would be happier and more alert.
13. The extra oxygen would improve our cognition, alertness, and phisical performance.
14. But there would be giant insects.
An insect’s body size is determined by the proportion of oxygen in the atmosphere.
