水的温度降到0℃以下就从液体变成固体——冰,一切可燃液体温度降低到一定程度也要凝固,从变成稀稠状物态,直至变成固态,从液态变成固态时的温度叫凝固点。不同的液体,它的凝固点是不一样的。例如,优质汽油,它的凝固点就很低,在自然温度条件下,它是不会凝固的;而柴油,凝固点就比较高。例如,零号柴油,只能在温度高于0℃时使用;10号柴油,只能在温度高于
When the temperature of the water drops below 0 ° C, it changes from liquid to solid-ice. When all the flammable liquid is cooled down to a certain extent, it must also solidify, becoming a thin, thick matter until it becomes solid, changing from liquid to solid The temperature is called freezing point. Different liquids, its freezing point is not the same. For example, premium gasoline, which has a very low freezing point and is not solidified at natural temperatures, and diesel, has a higher freezing point. For example, zero diesel, can only be used when the temperature is higher than 0 ℃; No. 10 diesel, only at temperatures higher than
