教授走上讲台,提出了一个问题:“如何让水沸腾着结冰?”所有的学生都面面相觑,这完全是不可能的事情嘛!稍有一点物理常识的人都知道,水沸腾需要达到的温度是100摄氏度,而结冰需要的温度是0摄氏度,完全是两个极端,怎么可能实现“沸腾着结冰”呢?教授笑了笑,示意助手把一台带着透明玻璃罩的器械放到了讲台上。教授用烧杯倒了一杯自来水,然后把烧杯放进玻璃罩里。接着,教授让助 Professor came to the podium, raised a question: “How to make the water boil icing? ” All students are looked at each other, it is entirely impossible! Well, a little knowledge of the common people know that water boiling need Reached a temperature of 100 degrees Celsius, and the temperature required for icing 0 degrees Celsius, is completely two extremes, how can it be possible to achieve “boil with ice ” Professor laughed, indicating an assistant with a transparent glass Put the mask on the podium. The professor poured a cup of running water in a beaker and placed the beaker in a glass cover. Then, Professor help
