Would a Glass of Water Freeze or Boil in Space?

Here's a question for you to ponder: Would a glass of water freeze or boil in space? On the one hand, you may think space is very cold, well below the freezing point of water. On the other hand, space is a vacuum, so you would expect the low pressure would cause the water to boil into vapor. Which happens first?

Boiler (power generation)

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Boiler Feedwater Treatment (Part I): Why Water Treatment

At a pressure of 200 psig, for example, water boils at a temperature of about 388oF. At the critical pressure of 3200 psig (where water is converted to steam without change in volume), the boiling point is 704oF. As the pressure decreases, the boiling point of water decreases. Under vacuum water will boil at temperatures as low as 35oF.

Water Boiling Temperature vs Pressure in Vacuum Table Chart

Water in vacuum (or space) and temperature in space

(I know heat taken by vapor, and the water cool down, but I don't think it will be that cold, will it? In vacuum, boiling point is so low that water shouldn't need so much heat as it does in normal pressure, which means vapor actually takes more heat away under normal pressure than in vacuum, so water under normal pressure would be cooler?

Why does water boil in a vacuum? : askscience

Now you can imagine that if you reduce the external pressure, the boiling point will also drop. You can clearly see this from a phase diagram of water. As you decrease the pressure, the boiling point keeps decreasing, until it reaches 0.01 °C at the triple point of water (the lowest pressure at which liquid water exists).
