? It can be seen that water has a characteristic: when its volume is as small as 4℃ and frozen to ℃, its volume will be larger than that of water at room temperature. Tofu usually has a lot of water and seems to be packed in countless small tofu containers.
? Some of these small tofu containers are connected and some are closed. When the temperature is below zero, the size of each small tofu container and the distribution of water are irregular. When tofu is cold below ℃, the water in tofu will freeze. As soon as water freezes, its volume becomes larger, and the walls of every small tofu container are crowded around. Snowflakes are hexagonal, mainly because water vapor molecules are relatively sparse. When they condense, they are not affected by external unbalanced pressure. Finally, the whole tofu is compressed into a network.
? After the ice melts, the compressed watercress will not recover, and there are many holes in the frozen tofu, and the ice crystals form their shapes at their own angles. In fact, the ice crystals of large ice cubes are also hexagonal and intertwined, so we can't see them; Just like small salt, we can see that it is a hexahedral crystal, but big salt can't see what it is. Entangled together, we can't see the clouds; At home, it is a hexahedral crystal, but big salt can't see the ice flowers on the glass window. After the ice crystals condense, the surroundings gradually develop. At this point, the situation has improved. Sometimes the wind is strong, sometimes the wind is small; Some glasses are smooth, some are rough, some are slightly scaly, and some are spotless.
nine cold days, get up in the morning and look at the window, ah! There are white flowers on it: some like orchids, some like masson pine, and some like flowers. Who painted so many beautiful pictures on the glass overnight? Who else but nature? It froze in the cold. Ice? We have all met. If it's not in water, it's like a snowflake hexagon, but who has seen it like orchids and masson pine? Have you ever seen ice like orchids or masson pine? Yes, there is a lot of ice in the water, because water molecules are dense. When a large amount of water is frozen, ice crystals are intertwined.
