课堂上,我提出了这么一个问题:“当气温是0℃时,冰水混合物将如何?”不想,话音刚落,李明同学马上举手发言.他说:“由于冰水混合物的温度是0℃,与气温相同,它们之间不发生热传递.因此,冰水混合物中的冰既不吸热熔化,水也不放热凝固,冰与水的数量和温度都不发生变化,还是0℃.”“李明说得不对”王小聪同学迫不及待地边说边站了起来,连起码的“规距”都忘了.他说“因为液体在任何温度下都要蒸发,冰水混合
In class, I asked such a question: ”When the temperature is 0 °C, what will be the mixture of ice and water? “ Do not want to, the voice has just dropped, and Li Ming immediately raised his hand to speak. He said: ”Because of the ice water mixture The temperature is 0°C, and the temperature is the same, and no heat transfer occurs between them. Therefore, the ice in the ice-water mixture neither absorbs heat nor solidifies, and the quantity and temperature of ice and water do not change. Still, 0°C."” Li Ming said it wrong “Wang Xiaocon couldn’t wait to stand up and stand up. Even the minimum gauge distance was forgotten. He said ” because the liquid is at any temperature To evaporate, mix with ice water
