If you opened a bottle of water on the moon, waht would happen? b/c it is H2O in it and space has no oxygen.?

b/c space (as far as i know) has no oxygen. would it explode making a balck hole? or do nothing and just float there?? it's just a random question, but im bored. so yeah. and i mean like on the surface of the moon. just an astronaut opening a bottle of water...

Like everyone said, it will boil. To answer the last answerer's question, it will NOT heat up. Whatever temperature it starts out as, it will evaporate so fast the bubble form. (This is called boiling. It's the same boiling like a pot of hot water, but at a lower temperature). As the water boils, it gaseous water will take heat with it, leaving the liquid water colder so it's possible the remaining water will freeze them sublime. Whether it gets cold enough to do freeeze like this I think depends on the starting temperature, whether you're doing this in the sun or shade, and the starting quantity of water.
Reply:It would begin to boil, then it would freeze. Then the remaining ice would slowly sublimate and disappear. It does not matter for gravity if there is an atmosphere. And atmospheric composition does not matter for the thermodynamics of the problem. Oxygen or Helium... it's all the same.
Reply:As other people have already answered, it would first boil, because of no pressure, then freeze because of no heat. The passage from gas (boiling) to solid (ice), as someone else told you, is called sublimation; something that also happens on earth. E.g. you can dry your clothes even in sub-zero temperature because in the very dry air found in polar regions (I live in Norway) the air is so relatively dry (40% or less on the hygrometer) that it will sublimize.
Reply:The same thing that would happen on Earth, there is gravity on the moon still.
Reply:Well I'm not 100% sure, but I think it would freeze, or since it would be in a flimsy little plastic bottle, it would probably already be frozen, because the temperature in space is really really cold. But maybe the unfiltered sun light would keep it liquid, I don't know.


What I do know is that it wouldn't necessarily explode, and surely wouldn't make a black hole. It wouldn't explode unless it was under pressure in the bottle (which it would be if it had been bottled on Earth), and it wouldn't make a black hole because those are made when stars die, not when we open bottles of water in space.
Reply:Will boil. The boiling reduce the temperature and the water become ice. The ice subliminate too...





In the Moon there are near zero pressure. The boiling point is related to the pressure, so in the Moon the liquid water will start to boil as soon as you open the bottle.





In the space there are vry small quantities of gases, like a molecule / cubic centimeter. (about 90% hydrogen, 9% He, and other gases %26lt; 1%)
Reply:thanks for this question... with the answers you're getting, now I get to ask one, too....





when you guys say 'boil' are you meaning just that the water 'roils' as the bubbles of the gas leave the liquid or are you saying 'boil' as in it's suddenly hot and boiling like on the stove?....





thanks for letting me horn in on your post.....*smile*......
Reply:It would boil away rapidly into the vacuum of space there, in a matter of seconds.
Reply:It would boil. The boiling point of water decreases as the atmospheric pressure decreases, so since the pressure on the moon is zero, it would immediately boil.


And by the way, black holes are NOT created by explosions as small as a bottle of water. If they were, the things would be all over the place every Fourth of July.
