    如何阻止水結冰! (How to STOP Water From Freezing)

    03:55如何阻止水結冰! (How to STOP Water From Freezing)
    • The basic reason supercooling is possible in the first place is that the formation of ice crystals in water has two competing factions, the interior and the surface. The interior of ice has less energy than liquid water, so the interior wants to freeze. But the surface of ice, the boundary between the ice and the liquid water, the surface actually takes more energy to form than if it just stayed liquid, so it wants to stay liquid. Who wins? Well, volume is a multiple of the radius cubed, but surface area is only a multiple of the radius squared, which means big things tend to have proportionally large interiors, while small things tend to have proportionally large surfaces. So a really, really tiny ice crystal will have proportionally way more surface than interior, and the surface's desire to melt will win over the interior's desire to freeze. In supercooled water, any really tiny ice crystals that form melt back into liquid. Only once you get a large enough ice crystal – and the exact size depends on the temperature – only with a large enough ice crystal is the interior proportionally big enough that its desire to freeze wins out over the surface, and the crystal can grow bigger and bigger and bigger. At negative 4 degrees Celsius, the tipping point is when crystals get larger than around 20 nanometers in size, aka about 70 water molecules across. At colder temperatures, the tipping point is smaller – for example, at negative 10 degrees Celsius, you only need a crystal larger than around 10 nanometers in size, about 30 molecules across. This battle between interior and exterior is why pure water cooled below the freezing point won't necessarily freeze right away – it remains as a supercooled liquid and has to wait until a crystal forms that's bigger than the tipping point and can keep growing and freeze the whole bottle. Which can happen by waiting, or by cooling the water more so the tipping point crystal size gets smaller, or if you have other stuff like minerals or dust particles in the water that can jumpstart the ice crystal formation by being bigger than the tipping point, or if you provide a jolt of energy, like by smacking the bottle. Then a crystal can get above the tipping point size and freeze.

      超冷之所以可能,首先是因為水中冰晶的形成有兩個相互競爭的派別,即內部和表面。冰的內部能量小於液態水,是以內部希望結冰。但是冰的表面,也就是冰和液態水之間的邊界,表面形成冰晶實際上比保持液態水需要更多的能量,所以它想保持液態。誰贏了?體積是半徑立方的倍數,但表面積只是半徑平方的倍數,這意味著大的東西往往有相應大的內部,而小的東西往往有相應大的表面。是以,一個非常非常小的冰晶的表面積將遠遠大於內部面積,表面的融化慾望將戰勝內部的凍結慾望。在過冷的水中,任何形成的微小冰晶都會融化成液體。只有當冰晶足夠大時(具體
