tech19 Posted January 9, 2009 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 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.
jrayj Posted January 11, 2009 Posted January 11, 2009 Yeah, liquid oxygen would just freeze your lungs.
