一杯冷水和一杯热水同时放入冰箱的冷冻室里,哪一杯水先结冰?很多人都会毫不犹豫地回答:“当然是冷水先结冰了!”非常遗憾,错了。发现这个错误的是一个非洲中学生姆佩姆巴。1963年的一天,坦桑尼亚马干巴中学的初三学生姆佩姆巴发现,自己放在电冰箱冷冻室里的热牛奶比其他同学的 A cup of cold water and a cup of hot water are placed in the freezer of the refrigerator at the same time. Which cup of water will freeze first? Many people will answer without hesitation: “Of course, the cold water is freezing first!” Very sorry, wrong. What found this mistake was Mpemba, an African high school student. On the day of 1963, Mpemba, a junior student of Makamba Junior High School in Tanzania, discovered that his own hot milk in the refrigerator freezer was more than that of other students.
