Ice Formation (1 of 3) (IMAGE) University of Utah Caption The box here is full of liquid water, which is not shown (white). Supercooled liquid water starts to become “intermediate ice” (green) on the way to freezing into ice (red) well below the 32 degrees F that people normally consider water’s freezing point. University of Utah chemists calculated that supercold water finally must freeze at minus 55 F.
