ORIGINAL: mnottertail I will put you in a room with fire, and you see how long you can breath in it. It certainly draws, sucks, inhales, aspirates, imbibes, consumes................oh hell you get the idea......................Oxygen from the air. Fire is a chemical reaction in which an object reacts with oxygen at a certain temperatures. <<<<<<<<<<<<< your blurb. now, do we have to get down to cases on 'reacts'? as such it is aspirated, and its natural. When there is no oxygen, there is no fire. Fire extinguishing methods exclude air (oxygen) from reacting that is...............atomically combining a fuel and an oxidizing agent (oxygen) and picking up free radicals. Natural aspiration has little or nothing to do with zero gravity or any gravity we exist in. Your non-sequitur is 'inoperable' sucking may not be vacuum here. Please see any naturally aspirated forest fire of any size for atomspheric changes. I cannot buy your assumptions, therefore I cannot buy your deal. (and explain the exploding windows in a house fire left unattended). see, we have this thing where hot air rises, and there becomes a difference in pressures between hot and cold, even a reactionary would not say that hot air descends would they? But to sharpen the point, the observers of this round ball of flame, did they naturally aspirate while performing the experiment or would that also be unnatural? Incorrect, The thermal energy produced by the reaction is absorbed by the surrounding air, causing it to circulate via thermodynamics and gravity (hot air rises, cold air descends) which is what causes more air is pushed into the combusting materials. For Aspiration to occur naturally - AS PER YOUR DEFINITION - it would have to suck air into the flame with out any other external forces being applied to it. And if we put it in exactly those conditions, like in zero gravity, the flame does NOT produce a vacuum effect drawing in extra air, and instead produces a ball of burning material which eventually sputters out once all the fuel in it's area of effect is consumed. You are contradicting your Own definition. oh, sorry, you again must stand in a fire in a room with no circulation. You will not be burned. Tell me all about your breathing skills. we do not live in zero gravity and fire burns and people breath in it. Further your experiment, add more gasoline in the confined space, and watch it burn in a ball. We live in a real world. A fire will burn as long as there is fuel and oxygen (its really rusting is what it is doing). assume all the fuel in the world if you must. and exactly 2 sq ft of 02 in the world and it is available to the burning organic matter. It will last forever, go!!!! let us see the equation again, a wildfire burns, and there is no lack of organic material and zero oxygen. What is the burn time? is the burn time equal to the flame or fire? if not, why not?
