Discussion Overview

The discussion revolves around the possibility of transforming hydrogen into different gases, including oxygen and methane, under specific temperature and pressure conditions. Participants explore various chemical processes and reactions related to hydrogen and its interactions with other elements and compounds.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests that hydrogen might change into different gases under certain temperatures and pressures.
  • Another participant challenges this idea, stating that only nuclear processes like fission and fusion can change one element into another, and clarifies the distinction between oxygen and carbon dioxide.
  • A third participant proposes that the discussion may relate to coal gasification processes, which involve generating methane and carbon monoxide from water and carbon.
  • Further, a participant mentions specific gas shift reactions that can occur with hydrogen and carbon.
  • Another participant introduces the concept of turning hydrogen into plasma and suggests that under high pressure, it could combine to form helium, referencing processes that occur in the sun.

Areas of Agreement / Disagreement

Participants express differing views on the transformation of hydrogen into other gases, with some proposing chemical processes while others emphasize the limitations of elemental transformation. The discussion remains unresolved regarding the initial claim about hydrogen changing into oxygen.

Contextual Notes

There are unresolved assumptions regarding the conditions under which hydrogen might change states and the definitions of the gases discussed. The discussion also reflects a mix of chemical and nuclear processes without clear consensus on the mechanisms involved.

ive heard that hydrogen under certain temps will change into diferent gasses like oxygen and methane. if we could grab a crap load of hydrogen and other gasses under certain pressure and heat would they change gasses.

I'm not sure what you heard exactly, but it doesn't sound right. Only through fission and fusion can you change one element into another. Perhaps you heard about converting water into hydrogen and oxygen? Water is already hydrogen and oxygen, just in a different molecular form.

Also, CO2 is carbon dioxide. Oxygen is oxygen - molecular oxygen is O2.
 
It sounds like some sort of coal gasification process involving water, generating methane and carbon monoxide.
 
That's the gas shift reactions, some of which are:

H2O+C(solid)=> H2 + CO
2H2+C=>CH4
...
 
If you turn hydrogen into plasma(superheated gas) and then apply a whole lot of pressure, the hydrogen will combine and form a different element, probrably helium. Thats what keeps our sun running
