Sorry but after yours "Hydrogen, in a gaseous state is just H" I assumed
that it will be helpful. This is shorter:

That " it appears". Where can we read about this? H and Pt make something
like alloy. May be that heat of solution is high.

Before study "must* have been done a description of the phenomenon. Can
anybody help?

"hot" is closee to warm, not to Visible light EM

It seems that there was the oxygen.
