The hotter a substance, the faster and the less ordered…
““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
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
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.
