What condition must be met to cause the phenomenon known as vacuum freezing of liquid water?

Answer

Rapidly lowering the pressure

Vacuum freezing occurs when liquid water is exposed to a strong vacuum, causing its boiling point to plummet. The energy required for this rapid boiling is drawn from the water itself, causing a drastic cooling that can lead to ice formation.
