Why does ice maker use flowing water to make ice transparent, and ice made from still water is milky?
Why is the ice made from still water Milky?:Because the water dissolved a certain amount of air, formed into ice, the density becomes smaller, the air out, and because the ice is solid, the precipitation of gas can not escape, so stay in the ice, after the refraction of light, looks milkyWhy is ice made from flowing water transparent?:Because the flowing water is relatively fast and the dissolved air is less, it looks transparent. If you look carefully, you can see that it is not that pure transparent
There are a lot of defects, so the white hair (bubble and pore); the flow of the water is not easy to crystallization, may have begun to generate 1 to several nuclei, grew up on this basis, the formation of the crystal is perfect, so transparent.For example, the difference between ordinary quartz and crystal.
It may be that the still water is easy to freeze. From the point of view of crystallization, many crystals are produced at the same time, and then they grow up. The crystals formed are not perfect,
