Well, considering how energy-dense it is... As a construction material, wouldn't it be more than a tad dangerous if it ever caught on fire?
- TrainedMonkey 12y agoGiven temperature and pressure it formed at I am not sure oxidation would be a problem at all.
- andrewflnr 12y agoIt wouldn't so much catch on fire as revert to gas, straight from solid to H2. Otherwise known as an explosion. Then maybe you get burning hydrogen.
- ars 12y agoOh, there will be fire. The amount of energy going from H to H2 is more than there is from H2 to H2O. If this really is atomic hydrogen it holds a ferocious amount of energy. https://en.wikipedia.org/wiki/Atomic_hydrogen_welding https://en.wikipedia.org/wiki/Atomic_hydrogen_welding
- andrewflnr 12y agoYes, my point was that it doesn't make any sense to call that a fire. H(s) to H2(g) is a highly exothermic phase change. Fire is oxidation.
- ars 12y agoThat's not a phase change (despite the solid to gas), that's a chemical reaction. Fire is oxidation yes, but despite the name oxidation does not require oxygen, it just requires electron transfer, which happens here.
