Water Molecules Quote by Henning Genz
““The hotter a substance, the faster and the less ordered its molecular motion, and the larger the momentum with which molecules collide. Above 0 degrees Celsius, the water molecules collide so frequently and so violently that no structure can appear or be sustained. Should there be somewhere in the water a small piece of ice, it's molecules will be rent asunder by the momentum of the surrounding molecules. It is only at 0 degrees that the number of these hits and their impact no longer suffice to destroy incipient structures: The water can now freeze into ice.””
About This Quote
Source Book: Physics of Water, Henning Genz, 2015
Water freezes only when molecular collisions become gentle enough for ice structures to form, which occurs at 0 °C.
In simple terms: Ice forms when molecules move slowly enough.
Key Takeaway
Cool water to 0 °C to freeze.

A Different Perspective
Above 0 °C, constant collisions prevent any ordered structure from persisting.
