When a snowflake gets heavy, it will fall to the ground. Snowflakes are formed when water vapor in the air condenses and freezes into ice crystals. These ice crystals then clump together with other ice crystals to form a snowflake.
短文第二段中间指出 This glucose, in turn, lowers the temperature at which the liquid inside the frog's cells freezes. 意为这种葡萄糖可以降低 wood frog 细胞液体结冰的温度。由此可知这种葡萄糖使细胞里的水不会结冰,故选 A 。 3 、 D [ 解析 ] 细节题。根据短文第三段前半部分 help them ...
What happens when you spread salt crystals over an icy sidewalk? Why is this procedure rarely used in very cold climates? Freezing and melting point Each liquid has a point where it starts changing liquid into solid. Similarly, every liquid turn soli...
