Where the hell did you learn science? I'm currently meant to be revising for an exam on fluid dynamics, and I can tell you right now that liquids can exist wherever the hell they please, including in a vacuum. Whoever told you that liquids can't exist in a vacuum is a complete and utter fool.Thedutchjelle said:If you melt something, it becomes liquid. Liquids can't exist in a vacuum.Dangernick42 said:I was thinking, cuz i kno that if u get a tree hot, it burns. But what if you heated it up in a vaccuum, theres no oxygen so it cudnt combust, but the heat energy is still being applied. I want liquid tree!!!
No; the melting point of water is dependent on the ratio of H:O, not the ratio of their masses. I suggest you look up `hydrogen bonding'.mysoxsmell said:Thedutchjelle said:You could try that. NItrogen is usually used, but even a inert gas might react under extreme temperatures.Hurr Durr Derp said:My chem knowledge sucks, but what if, in stead of using a vacuum, you'd just replace the air with some inert gas or something?Thedutchjelle said:If you melt something, it becomes liquid.

I want liquid tree!!!Melting points can't really be estimated that way - the melting point can be vastly different if it's in a molecule due to the bonds between various atoms. Hydrogen has a melting point of -259 C , but water, which consists 2/3 of Hydrogen , only melts at 0 C.Daipire said:Even people can melt (and I'm not talking about raiders of the lost ark shit either) in a vaccuum and under high temperatures.
Find out what the main chemicals in trees are and simply get the melting temps for those. And people are carbon based, and carbon melts at 3500 Celsius.
The more you know!
I would also like to point out that wood and trees are biological, and biological matter tends to degrade very quickly if heated up that much, as all the enzymes and complex molecules break down...you might get a molten substance at one point, but I don't think that it can be considered wood anymore at that point.
I'm not an expert in chemistry, I'm just basing this of my 5 years of high-school chemistry knowledge (which will be tested in an exam within 4 hours D: )
well technically water isn't two thirds hydrogen, that may be the ratio of hydrogen to
oxygen but you must take into account the size of the atoms as well
seeing as oxygen is said to weigh 16 nano grams or some kind of gram while
hydrogen weighs 1 of said unit, so the actual ratio sits at about one to nine of every whatevergram of a water molecule being hydrogen
To be honest, I can't recall where I got that from. Interesting, I thought for a long time that liquids couldn't exist in vacuum.. I didn't had much lessons about pressure and vacuum during physics or chemistry, so my knowledge of this is rather limited, I'll confess. Can water exist in a vacuum then?Trivun said:Where the hell did you learn science?

and thisDeep vacuum lowers the boiling point of liquids and promotes low temperature outgassing...
So perhaps it's just water then? Or can really every liquid exist in a vacuum?Blood and other body fluids do boil when their pressure drops below 6.3 kPa, (47 Torr) the vapour pressure of water at body temperature.
Every single liquid will exist in a vacuum. Reason being that liquids come between gases and solids in the various states of matter. There are actually at least four that are known, after gases comes plasma (or rather, superheated gas to the point it's still gas but acts like liquid). Possibly more, but I'm not sure.Thedutchjelle said:To be honest, I can't recall where I got that from. Interesting, I thought for a long time that liquids couldn't exist in vacuum..

OT:
Perhaps it's time for a new video series
"Will it melt? That's the question."
Errm... No. In a vacuum at a hich temperature, people explode. You can try and argue that the remains would melt, but as others have said before, it wouldn't really be a person anymore.Daipire said:Even people can melt (and I'm not talking about raiders of the lost ark shit either) in a vaccuum and under high temperatures.
