问题:什么液体决不会把东西弄湿? 答案:汞。这是唯一在室温下呈液态的金属。此外,它还有其他不同寻常的特性。汞的密度很大,就是说它的分子结构相当紧密。因此,它不易附着在别的东西上。橡皮擦能在一滴汞上划出一道凹痕,但不会被弄湿。汞在遇热或遇冷时膨胀或收缩的速度是一样的,由于这一特性,它是制作温度计的理想材料。它还能导电,因此用于某些电池和荧光灯中。汞的颜色为银色,流动滑畅迅速。人们有时叫它水银。千万别碰水银,它可是有毒的。 Question: What liquid will never get wet? Answer: Mercury. This is the only metal that is liquid at room temperature. In addition, it has other unusual features. The density of mercury is large, which means that its molecular structure is quite tight. Therefore, it is not easy to attach to something else. The eraser can mark a dent in a drop of mercury, but it will not get wet. Mercury expands or contracts at the same rate when exposed to heat or cold, and due to this property it is an ideal material for making thermometers. It also conducts electricity and is therefore used in some batteries and fluorescent lamps. The color of mercury is silver, and the flow is smooth and rapid. People sometimes call it mercury. Do not touch mercury, it is poisonous.
