Hot tap water will freeze before cold distilled water, if you control for all other conditions, because the impurities in the tap water mean that it just...freezes at a higher temperature.

如果控制所有其他的条件的话，水龙头流出来的热水比冷的静止的水结冰要快，因为水龙头水的杂质会让水在更高的温度结冰。

I love having really hot tap water for this reason, I'll just fill this up and let it sit until I'm ready to pour into it.

出于这个原因， 我喜欢喝非常热的自来水，我会把它装满， 让它静置，直到我准备好倒进去。
