时差N小时 为什么盐能加速冰融化?(下)

Since there are now fewer liquid water molecules¹ to be captured and frozen by the ice, the rate of freezing drops.

既然结冰的液态水分子减少了，冰点自然降低了。

I think I get it. And Since the rate of melting stays the same, there's more melting going on than freezing.

我明白了。水的熔点不变，融化的水分子比结冰的多，

And so the ice melts.

所以冰块就融化了。

Right. Interesting.

对。很有趣。

In fact, anything that dissolves in water will do the trick.

其实，任何溶于水的物质都可以使冰融化。

You could pour sugar on ice and it will melt.

把糖洒在冰上，冰也会融化。

But I guess since salt is cheaper it's used more often.

但是我想也许由于盐比较便宜，所以经常被使用。

分子( molecule的名词复数 )

参考例句：

• The structure of molecules can be seen under an electron microscope. 分子的结构可在电子显微镜下观察到。
• Inside the reactor the large molecules are cracked into smaller molecules. 在反应堆里，大分子裂变为小分子。
