Kyshakk Koan Monroe Posted March 14, 2010 Share Posted March 14, 2010 Burning implies changing the molecular structure of something. Ice melts when fire is involved, but water has the same molecular structure as ice, so it did not actually burn while melting. There might be some kind of process that involved turning frozen H2O into something that is not water that I do not know of. No, ice can not be set on fire if that's what you are asking. Mainly because ice does not exist at the same temperatures that fire exists at. Technically neither of them exist at room temperature.

Aside from the fact that you would probably break up the molecules anyway, since the atoms would no longer be hydrogen and oxygen the resulting material would not be water. Transmutation of elements is really simple, just also really impractical. Quote Link to comment Share on other sites More sharing options...

Easygoing Eyebeast Dantius Posted March 14, 2010 Share Posted March 14, 2010 I think that you can explode dry ice (solid nitrogen),m and you can do all kinds of cool stuff with liquid nitrogen, but standard H20 ice is pretty boring. Quote Link to comment Share on other sites More sharing options...
Well-Actually War Trall A less presumptuous name. Posted March 14, 2010 Share Posted March 14, 2010 Originally Posted By: Dantius dry ice (solid nitrogen) Dry ice is solid Carbon Dioxide. And liquid nitrogen is much colder than dry ice. So clearly they can't be the same compound. Quote Link to comment Share on other sites More sharing options...
Kyshakk Koan cfgauss Posted March 14, 2010 Share Posted March 14, 2010 Combustion reactions are oxygen plus some other reactant, often made of some hydrocarbon in the usual kinds of ones we see... So, no, there's no reaction of H2O + O -> stuff. There is however, a reaction, 2H + O -> H2O + heat So you can burn hydrogen to give you water. But water will not burn in that sense. edit: Some about the chemistry of water on wikipedia's better-than-average but still disorganized and not so well-written page on H2O, http://en.wikipedia.org/wiki/H2O Quote Link to comment Share on other sites More sharing options...
Understated Ur-Drakon Celtic Minstrel Posted March 15, 2010 Share Posted March 15, 2010 No, you cannot burn ice. Burning involves adding oxygen, so you can't burn things that are already oxygen-saturated, such as water or glass. Quote Link to comment Share on other sites More sharing options...

What I've always wondered is when happens when you try to boil water in a paper container over a campfire. Quote Link to comment Share on other sites More sharing options...
Hatchling Cockatrice Alorael at Large Posted March 15, 2010 Share Posted March 15, 2010 If the paper is permeable to water, it may or may not burn sluggishly. It probably will char, though, until the water bursts through the bottom. If the paper is waxed, it will catch on fire, a hole will burn through the bottom, and the water will dump out. —Alorael, who has determined these truths through rigorous, double-blind thought experiments.

Kyshakk Koan cfgauss Posted March 15, 2010 Share Posted March 15, 2010 I recall seeing someone boil water in a plastic container on one of those discovery channel survival shows (I forget which). I think they wrapped it in green leaves or something though.

Magnificent Ornk Student of Trinity Posted March 15, 2010 Share Posted March 15, 2010 Old Boy Scout manuals used to tell you that you could boil water in a folded paper cone. I've read it in a couple of them. It might have been important not to get the paper too close to the flame, but I'm not sure. What I don't clearly recall at the moment is how you were supposed to hold the cone over the fire at all without cooking your fingers. Some tricky construction with sticks, I expect, that might have worked better with 19th century paper. Or maybe they imagined that you'd have paper and string, or even wire, but no pot. I've never tried it. Any times I've been out in the wilderness with the makings of a fire and potable water on me, I've also had a metal cup, and more interest in getting some hot coffee than in testing bizarre cooking techniques.

Hatchling Cockatrice Lilith Posted March 15, 2010 Share Posted March 15, 2010 Paper conducts heat pretty well, and water is a great heat sink. The paper will reach 100 degrees Celsius, at which point the evaporation of water prevents it from getting much hotter. On a related note, if anybody ever bets you that you can't hold a dollar note against your forearm for long enough to burn through it with a cigarette, don't take the bet.

I suppose, but hydrogen peroxide isn't as stable as water. So it'd have to be in an oxygen-saturated environment, I guess. Quote Link to comment Share on other sites More sharing options...

Especially not if if you stand to win less than a dollar. I'll concede them unlimited expertise in bar bets, but what do Australians know about paper currency, anyway? Your dollar notes are plastic. Canada is going to copy this soon, and actually buy its notes from Oz. For how much? Hmm. Quote Link to comment Share on other sites More sharing options...
Hatchling Cockatrice Lilith Posted March 15, 2010 Share Posted March 15, 2010 We don't actually have dollar notes anyway. Everything up to $2 is a coin; the smallest denomination of banknote is $5. Quote Link to comment Share on other sites More sharing options...
Magnificent Ornk Student of Trinity Posted March 16, 2010 Share Posted March 16, 2010 That's true in Canada as well, in fact. Presumably because it's part of the global currency convergence conspiracy of the Gnomes of Zurich. Already, all US and Canadian coins are of exactly the same sizes, except that there is not yet any US $2 coin. Quote Link to comment Share on other sites More sharing options...

Magnificent Ornk Dikiyoba Posted March 16, 2010 Share Posted March 16, 2010 So basically all $2 bills get their start in strip clubs and eventually meet their end in the piggy banks of people who collect them because they're somewhat rare.

Hatchling Cockatrice Randomizer Posted March 16, 2010 Share Posted March 16, 2010 I have a friend who used $2 bills for buying lunch because he hated the cashier and loved to see her struggle to lift the cash drawer out to put it away. Cash drawers don't have a space for them. Back when Wall Street was booming some stock traders would go to the Federal Reserve cash window and buy bricks of them on Friday to pay for a weekend of partying.

Magnificent Ornk Dikiyoba Posted March 16, 2010 Share Posted March 16, 2010 Lilith knows everything. Also, that fact is on the $2 bill's Wikipedia page so it's not like it's super top-secret knowledge. Dikiyoba. Quote Link to comment Share on other sites More sharing options...
