tech19 Posted January 9, 2009 Share Posted January 9, 2009 New to organic chemistry and I'm only in high school chemisty. I heard from some where that if given time humans could stop breathing gasous oxygen and switch to liquid oxygen. I looked up the requirements to maintain liquid oxygen you need to keep it at -118 degrees so what would you chemically combine with this substance to raise the temperature at which it becomes gasous.

insane_alien Posted January 9, 2009 Share Posted January 9, 2009 the 'liquid oxygen' used for liquid breathing isn't actually liquid oxygen. its a fluid that can cary a high concentration of oxygen and carbon dioxide. where the oxygen and carbon dioxide are dissolved in the fluid. breathing true liquid oxygen would be fatal. EDIT: from http://en.wikipedia.org/wiki/Liquid_breathing seems they use perfluorocarbons as a medium for oxygen transportation. Link to comment Share on other sites More sharing options...
jrayj Posted January 11, 2009 Share Posted January 11, 2009 Yeah, liquid oxygen would just freeze your lungs. Link to comment Share on other sites More sharing options...
