请问水在任何情况下都是热胀冷缩的对吗？常温

　　请问水在任何情况下都是热胀冷缩的对吗？常温下的水是否具有热胀冷缩的性质「干货」

　　最近有很多热心网友都十分关心请问水在任何情况下都是热胀冷缩的对吗？常温下的水是否具有热胀冷缩的性质「干货」这个问题。还有一部分人想了解水在任何情况下都是热胀冷缩的对吗。对此，和记百科小编「陌上﹏烟雨瑶」收集了相关的教程，希望能给你带来帮助。

常温下的水是否具有热胀冷缩的性质

　　常温下的水具有热胀冷缩的性质，常温下的水通常是指20摄氏度左右。在4℃以上时，水温降低，分子间距的变化会起主导作用，这时的水具有热胀冷缩的性质。而在4℃以下时，温度越低，氢键就会越多，导致体积增大，这时的水不具有热胀冷缩的性质。

　　水的特性有沸点高、蒸发热大、热容高、反常膨胀、良好溶剂、能不断发生缔合共六种。水，是由氢、氧两种元素组成的无机物。在常温常压下为无色无味的透明液体，被称为人类生命的源泉，是维持生命的重要物质。纯水导电性十分微弱，属于极弱的电解质。日常生活中的水由于溶解了其他电解质而有较多的阴阳离子，才有较为明显的导电性。

水在任何情况下都是热胀冷缩的对吗

　　问题：水在任何情况下都具有热胀冷缩的性质。这句话是否正确？如果不正确，请指出错误，并改正过来。

　　正确答案：【解析】水在任何情况下都具有热胀冷缩的性质这句话是错误的。水在4℃以上具有热胀冷缩的性质，而在之间的水会热缩冷胀。【答案】见解析。

　　【英文介绍/For English】：

　　Water at room temperature has the property of thermal expansion and contraction, and water at room temperature usually refers to about 20 degrees Celsius. When the temperature is above 4°C, the water temperature decreases, and the change of molecular distance will play a leading role. At this time, the water has the properties of thermal expansion and contraction. When the temperature is below 4 °C, the lower the temperature, the more hydrogen bonds will occur, resulting in an increase in volume. At this time, water does not have the properties of thermal expansion and contraction.

　　The characteristics of water are high boiling point, large heat of evaporation, high heat capacity, abnormal expansion, good solvent, and continuous association. Water is an inorganic substance composed of hydrogen and oxygen. Under normal temperature and pressure, it is a colorless, odorless, transparent liquid, known as the source of human life, and an important substance for sustaining life. Pure water has very weak conductivity and is an extremely weak electrolyte. Water in daily life has more anions and cations because it dissolves other electrolytes, so it has more obvious conductivity.
