NordlichReitersays...Does water boil at the same temperature in space as it does on earth?
I was under the impression that pressure and the like cause materials to boil at different temperatures in different locales.
I am ill equipped to perform an accurate testing of the above hypothesis, seeing as I have no rocket ship. I am not willing to suffer the inaccurate answers of Yahoo or Wikipedia.
shuacsays...What about paint drying in micro-g?
Lucidiumsays...Boiling point lowers as pressure decreases. So at sea level the boiling point of water is around about 100˚C, but at the top of Mount Everest it's more like 70˚C. There's no real value for the boiling point of water in a vacuum, because it would be a gas at any temperature.
Edit: Actually, you can get solid water at very cold temperatures in space, but as you heat it up the water would transition straight from solid to gas, so it has a sublimation point instead.
The microgravity experiment was probably done in a shuttle or the ISS, which are pressurised to about the same as sea level so that it's comfortable for the astronauts.
