Would water in space boil at a very low temperature?
Liquid water can’t exist in a vacuum. As atmospheric pressure is lowered, the boiling point of water will decrease. Eventually, the boiling point approaches the freezing point and ice doesn’t “melt” it sublimates. If the temperature of the ice is raised above 0 C, it turns to a gas skipping the liquid phase. So, its not exactly “boiling”, but water ice turns to a gas at 0 C in a vacuum.
