## Freeze? Turns into gas?

Let's say you have water in liquid form in a closed container on a spaceship in space. Then you bring the container filled with water out from the space ship into free space.

Will the water freeze, stay in liquid form or turn into gas?

Assume the container didn't break.
 Assuming the container wouldn't break, the water would stay in liquid form. The pressure stays the same and the temperature doesn't change as well, so no phase transition for you :). ----- Assaf Physically Incorrect
 Oh, the temperature inside the ship and outside the ship is the same?

Once outside the water has no way of transferring heat - not by convection, nor by conduction (to what? there is nothing in space). It will radiate, but it would take it a looong amount of time to lost its heat energy that way.
 Mentor It actually doesn't take that long to radiate heat away. If shaded from the sun, it could freeze in a few hours. If not shaded from the sun, solar radiation would probably keep it warm (though I'd have to calculate that to be sure).
 So the water can, in fact be either in solid, liquid or gaseous state depending on how much is the container shaded from the sun?
 Ah, never said anything about the sun :). Exactly how far from the sun are we talking about? (and we ARE talking about OUR sun, right?) Assaf Physically Incorrect

As far as I know all material emit electromagnetic radiation because they contain charged particles which accelerate at random directions because of the thermal energy the object has.
If you have an object in a perfect vacuum far far away from any other objects,
why shouldn't it emit electromagnetic radiation ? as i see it - it emits the radiation because of its own properties and not only because of the environment.
I think it even should be cooled faster if it has no other object around it which can reflect back the radiation it emits, or radiate energy back to it.
Does it make sense what I say ?
 The water will not change if the container retains its volume, regardless of any influences. If the container changes volume then it's a whole different ballpark.

eh?

Anyway.. as other people said. What happens to it depends on how much radiation it receives.
