WebOct 22, 2007 · Liquid water and ice have only slightly different volumes, so the freezing point isn't very sensitive to pressure. To the extent that it is, higher pressure favors the liquid, which (somewhat unusually) has smaller volume.Since your bottle's pressure seemed to slightly rise when opened, that effect would actually tend to reduce freezing. However, … WebThe purification procedure reduces the concentration of contaminants such as suspended particles, parasites, bacteria, algae, viruses, and fungi.
