"WebFreezing Point of Water. The freezing point of any substance describes the point for the liquid to solid transition. The liquids can be super-cooled beyond their freezing points so that they don’t solidify until well below freezing point. The freezing point of water is 0 °C or 32 °F. The temperature may be lower if super-cooling occurs. " - How does lower pressure affect freezing point
