When you burn steel wool, it gets heavier.

@stux more importantly though, do you know WHY?

@stux The oxygen in the atmosphere around the steel wool is getting bound to the steel to make iron oxide, IIRC.

@artilectzed yup, so next question (let me know if you want the answer) why does a log get lighter when you burn it?@stux

@freemo @artilectzed I guess since it loses mass since it’s converted into a tiny amount of energy (tinitiny)

@stux Last time I checked logs arent nuclear reactions, lol I wish, but no... mass is preserved and energy is preserved both seperately in any sort of reaction you are likely to see, including burning of logs.@artilectzed

@freemo @artilectzed True! But even chemical reactions are the same in essence only very much smaller 🙂 Second is nuclear and best is gravitational

@stux Well no not really chemical reactions get their energy from stored bond energy not mass. In any chemical reaction the mass is exactly the same, down to the electron. It simply releases energy from bond energy.. There is never any change from mass to energy or back again.. it si a fundemental garuntee in chemistry.@artilectzed

@stux Wouldyou like the answer as to what makes a burning log different from a burning iron-wool? They are both oxidative reactions and very similar in principle.@artilectzed

@stux Well there are certainly differences, but they are both fuels burning in an oxidative reaction. Its actually something you will go "duh I knew that" once I say it :)@artilectzed

@stux I see why you are saying what you said now.. but no this has nothing to do with the log.I dont want to confuse the issue but this is a totally different tangent and the video is even a bit misleading. I can explain the video a bit better but its unrelated tot he question about the log I posited.There is a hint of truth in the video you posted of course. A burning log gives off light and looses some energy, that energy would cause an infentesimal amount of mass to be lost. But it is so little as to be impossible to measure.@artilectzed

@stux I really want you to get what happens in a log as compared to the steel wool because a lot of people kinda know the answer and kinda dont and it will be an eye opener for you I think, and others.Here is the thing, like i said both are the same sort of reaction, combustion of a fuel in an oxidative reaction.. and there is a key difference between them that causes steel-wool to get heavier and a log to get lighter... But before i answer it (and i will do that if it doesnt click cause I really want you guys to understand this cause its cool)... Think about it in reverseAs a tree grows from a seedling it starts as barely anything just a seed and turns into this massive very heavy tree... where did it get all its weight from? All the atoms that make it up, where did they all come from?@artilectzed @carver

@freemoThe atoms that go into a tree came from the surrounding environment(that is, air and soil and all the chemicals therein.)When a log burns, I'm guessing that the moisture within it turns to steam or internal gasses are released due to the combustion process. This pulls mass from the log into the air, giving a nice woody fragrance, but making the log lighter.Close?@stux @artilectzed

@carver Kind of you are right that it is lighter because things are getting pulled into the air.. Logs dont have much moisture though, although a lot of steam **is** produced it is water that didnt exist prior to the burning.the vast majority of the mass of wood is carbon, when it burns the carbon is is released and the result of the chemical reaction is water that didnt previous exist is created and carbon dioxide. The newly created water escapes as steam and the CO2 produces is effectivelly oxygen from the air carrying away carbon from the wood.The vast majority of the weight lost when a wood log burns is the carbon it is loosing and being carried away by the oxygen.So in short steel wool is an oxidative reaction where iron oxidizes with oxygen cause iron oxide, this is a solid and stick around so the weight increases.In wood its an oxidative reaction where carbon is being oxidized creating CO2, this in turn is a gas and is thus escaping into the air.@stux @artilectzed

@freemoSo wood is being converted to water? That's kind of a mind-bender! @stux @artilectzed

@carver Yes water and co2 :)the cool part is when you consider the reverse.. When trees grow almost all of their mass comes from the air, water and co2 (well the water falls out of the air and through the ground).But yea it consumes CO2 and water and light and produces sugar and oxygen.. when it burns it reverses this in some form.@stux @artilectzed
