问:最近天冷了,妈妈每天早上都要烧开水,水开了的时候就会有一股股的白雾冒出来,这是哪儿来的呢?答:这个问题提得真好!冬天的自来水温度大约在0摄氏度左右,而开水的温度是在100摄氏度左右,烧开水就是一个把自来水加热的过程。在这个过程中,随着温度的升高,会有很小一部分的水从液态(就是一般水的状态)转化为气态 Q: It was so cold recently that my mother had to boil water every morning. When the water was on there was a white mist coming out. Where is it coming from? Tap water temperature is about 0 degrees Celsius, while the boiling water temperature is about 100 degrees Celsius, boil water is a process of heating tap water. In the process, as the temperature rises, a small fraction of the water will be converted from a liquid state, which is generally water, to a gaseous state
