water boils at room temp under a vaccum. why not the vaccum of space?

Part of the answer is that space is not a true vacuum and also the temperatures are considerably lower than room temperature, but also objects in space have an inherent gravity meaning they tend to coalesce rather than disperse, depending on the inertia the water may even be drawn to the spacecraft as a skin.

It probably freezes so quickly in the subzero temperature of the space and also due to the sudden expansion into vacuum from a pressurised cabin, thus the adiabatic cooling makes the water freeze.

Boiling:when the vapor pressure of the liquid equals the ambient pressure, atmospheric pressure is 760 torr....A vacuum could be 1-0.01 torr. In the vacuum of space, the pressure is <10^-12 torr.

Hi. Usually the temp is so low that freezing takes place first.

Vaporization requires an atmosphere. There is no atmosphere in space.
