你知道水是液态的，你知道水的分子式是H2O，但你可能不知道，在室温条件下，水本来应该是气体。
比如硫化氢H2S和氨NH3这些类似的分子都是气体。只是因为水分子的粘性，将这些气体聚在了一起，水才成为了一种液体。
You know that water is liquid, you know that the molecular formula of water is H2O, but you may not know that at room temperature, water should be gas.
For example, hydrogen sulfide(H2S) and ammonia(NH3), these similar molecules are gases. It's only because of the viscosity of the water molecules that water becomes liquid.
你可能知道，水有三种状态，分别为：固态、液态、气态。但你可能不知道，水不止这三态，还有：超临界流体、超固体、超流体、费米子凝聚态、等离子态。
As you may know, water has three states: solid, liquid and gas. But you may not know that water is not only in these three states, but also in supercritical fluid, super solid, super fluid, fermion condensate and plasma.
你知道冷水温度更接近冰，但你可能不知道，热水比冷水结冰更快。这就是所谓的“姆潘巴效应”。但没有人知道这是为什么。
You know that cold water is closer to ice in temperature, but you may not know that hot water freezes faster than cold water. This is the so-called "Mpemba Effect". But no one knows why.
据说96%的人可以仅靠听觉就能分辨出倒入杯中的是热水还是冷水。
It is said that 96% of people can tell whether they are pouring hot water or cold water into the cup by hearing alone.
