| Oct 17, 2015 at 1:20 | comment | added | Jason Patterson | @chestermiller There are chunks of ice flying around the outer solar system that are fairly small (i.e. minimal gravitational attraction) that have been there for at least 4.5 billion years. At very low temperatures sublimation just about grinds to a halt in spite of the exceedingly low pressure. | |

fix grammar, add structure

| Oct 16, 2015 at 10:36 | comment | added | user21891 | Nice answer @michael but can u explain why In lab vaccum conditions , why the water first boils and than condenses ? Whats the difference in a Adiabatic closed vaccum flask here on earth and interstellar space , Should'nt the results be all the same ?? | |

Any heat initially contained within the body of water you release will be radiated outward away from the water towards the background temperature of interstellar space - ~ 2 to 3 deg K. | |

| Oct 15, 2015 at 12:18 | comment | added | tschoppi | From Wikipedia: "In cool, dense regions of the ISM [interstellar matter], matter is primarily in molecular form, and reaches number densities of 10⁶ molecules per cm³." | |

Now, the interstellar conditions imply extremely low pressure, far off the bottom edge of that plot. See, there is no liquid there, only vapours and ice. | |

| Oct 15, 2015 at 11:35 | comment | added | Ivan Neretin | Well, if you suddenly release some liquid water into the outer space, part of it will instantly evaporate and the rest will freeze. | |
