deltanova Posted January 7, 2006 Share Posted January 7, 2006 Does anyone know what pressure Hydrogen has to be at to be able to conduct Electricity? Thanks Tash. Edit: I am under the impression it is and incredibly high amount of pressure, close to the pressure of jupiters core. but was wondering if anyone had a rough estimate and a Number.

xeluc Posted January 7, 2006 Share Posted January 7, 2006 Here's a site that may interest you: Theory predicted that metallization would occur when the insulating molecular solid would transform to a metallic monatomic solid at absolute zero--0 degrees kelvin (K) or -460°F. For early metallic hydrogen theorists' date=' "sufficient pressure" was thought to be 0.2 megabars (1 bar is atmospheric pressure at sea level; a megabar, or Mbar, is a million times atmospheric pressure at sea level). Subsequent predictions pushed metallization pressure to as high as 20 Mbar. At the time our experiments were conducted, the prevailing theory predicted 3 Mbar for solid hydrogen at 0 K.[/quote'] Link to comment Share on other sites More sharing options...

jdurg Posted January 7, 2006 Share Posted January 7, 2006 Hydrogen, and any gas for that matter, will conduct electricity if at a VERY low pressure. Neon lights and gas discharge tubes all conduct electricity. If they didn't, we wouldn't be able to see the gas. Link to comment Share on other sites More sharing options...
deltanova Posted January 8, 2006 Author Share Posted January 8, 2006 but Neon is a larger element? Link to comment Share on other sites More sharing options...
xeluc Posted January 8, 2006 Share Posted January 8, 2006 yes it is Link to comment Share on other sites More sharing options...
deltanova Posted January 9, 2006 Author Share Posted January 9, 2006 sorry, i should have been more specific about what i was meaning. isnt neon a larger element, and thus more able to conduct electricity than hydrogen? Link to comment Share on other sites More sharing options...
jdurg Posted January 9, 2006 Share Posted January 9, 2006 The size of the element really doesn't matter. If you take any gas in existance and place it at a low pressure inside a sealed tube it will conduct electricity just fine. Link to comment Share on other sites More sharing options...
