Is hydrogen electrically conductive? Above 220 GPa, hydrogen became opaque and electrically conductive. At 260-270 GPa, hydrogen transformed into a metal as the conductance of hydrogen sharply increased and changed little on further pressurizing up to 300 GPa or cooling to at least 30 K; and the sample reflected light well.
Does hydrogen conduct heat or electricity? While hydrogen is typically a gas on Earth, it can be artificially compressed and cooled to become a liquid or a solid.
