Guest snowcrash Posted May 31, 2003 Share Posted May 31, 2003 I seem to remember back in grade school that I read an atricle about the early study of fire. The study stated that it was thought fire was an actual element itself and exsisted in everything. What was the name of this element?

In the early studies fire, water, earth, and wind the four elements which made up everything. Its a frequently known study that almost everyone knows about that was invented by some greek dude, which was later crossed out as impossible by some later scientist who said there was like thirty something elements. Don't remember names. Link to comment Share on other sites More sharing options...
JaKiri Posted June 1, 2003 Share Posted June 1, 2003 'Fire' was one of the greek elements (Fire, earth, air, water). It's not the same concept of element that exists in chemistry, which is a chemical with a unique number of protons. Fire is now understood to be an exothermic oxidation reaction (at least conventional fire). Link to comment Share on other sites More sharing options...
greg1917 Posted June 1, 2003 Share Posted June 1, 2003 In the 1700's it was believed all substances contained stuff called 'phlogiston'. things that burned quickly, wood etc, rapidly disspiated their quantity of phlogiston. fire was the act of phlogiston rapidly leaving its host substance. rusting was a slower release of the substance. Lavoisier (with the help of an English chemist called Priestly) eventually discovered oxygen. Link to comment Share on other sites More sharing options...

Radical Edward Posted June 2, 2003 Share Posted June 2, 2003 Originally posted by MrL_JaKiri The one where they burnt the mice? only by accident. the one I am thinking of is the one where they removed the oxygen, and demonstrated how this is bad for mice. It is probably a different experiment. Link to comment Share on other sites More sharing options...

greg1917 Posted June 2, 2003 Share Posted June 2, 2003 Yes, when they heated mercury it burned up a fifth of the air and when mice were exposed to this air they promptly died. when the red mercury oxide was heated at a higher temperature pure oxygen was obtained and it was observed that the mice were hyperactive in this environment. If they burnt mice it was probably due to the absurd amount of opium and hash they smoked in those days. Link to comment Share on other sites More sharing options...
