What happens if we pour water into Space?

                            Space is really, really cold (If we talk about going to interstellar space, far away or shadowed from any stars, the only temperature comes from the leftover glow). So, if you take water into space, it should freeze, right?

  

No! We might be familiar with the fact that water boils at a lower temperature at high altitudes, this is because there’s less atmosphere above you, and hence the pressure is lower. That is the reason water boils much faster on a mountaintop than it does at sea level.

So when water poured into space (outside of a spacecraft) would rapidly vaporize or boil away. In space, where there is no air, there is no air pressure. As air pressure drops, the temperature needed to boil water becomes lower.
