Interesting Facts About Gas
Did you know…
- The word gas was coined in 1650–60 by J. B. van Helmont (1577–1644), a Flemish chemist. It comes from the Greek word for chaos.
- Hydrogen is the lightest, most abundant and explosive gas on Earth.
- The atomic weight of Radon is 222 atomic mass units making it the heaviest known gas. It is 220 times heavier than the lightest gas, Hydrogen.
- High levels of O2 increase the flammability of materials and gases – at levels such as 24%, items such as clothing can spontaneously combust!
- It’s not just gas that holds a potential threat – dust can also be explosive! Examples of explosive dusts include polystyrene, cornstarch and iron.
- Autoignition temperature of a flammable gas is the temperature at which an ignition will take place, even without an external spark or flame.
- If you smell the rotten egg aroma of Hydrogen Sulfide from the decomposition of organic matter, you are smelling only 1ppm. Just 1,000 ppm of H2S is enough to kill you.
- Fluorine is the most reactive and most electronegative of the elements, making elemental Fluorine a dangerously powerful Oxidant. This leads to direct reactions between Fluorine and most elements, including noble gases Krypton, Xenon, and Radon.
- Xenon is the rarest non-radioactive gas element in the Earth’s atmosphere. It represents 90 parts-per-billion of the total atmosphere
- There are 17 gases in total, which can be found in the natural atmosphere on Earth. Only Oxygen and Nitrogen are found in large concentrations; 20.9476% and 78.084% respectively.
- Hydrogen Sulfide bubbling up from the sea may have caused a global extinction of
- flora and fauna nearly 250 million years ago.
- ATEX (an abbreviation of ATmospheres EXplosibles) sets the minimum safety standards for both the Employer and Manufacturer regarding explosive atmospheres.
- Jupiter – our solar system’s largest gas giant – contains about 90% Hydrogen and 10% Helium. In fact, its composition is actually very similar to a primordial Solar Nebula (the type of Nebular that our solar system developed from).
