(单词翻译:单击)
Since there are now fewer liquid water molecules 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 。
