初中物理中常见这样一道题:为什么一般来说冰水混合物的温度总保持0℃?参考答案的解释为:因为冰的熔点和水的凝固点都是0℃,如果外界温度高于0℃,则冰要吸热熔化,而冰在熔化过程中保持0℃不变;如果外界温度低于0℃,则水会放热再凝固,而水在凝固的过程中也保持0℃不变;如外界温度等于
A common question in junior high school physics is: Why is the temperature of ice-water mixture always kept at 0°C? The explanation of the reference answer is: because the melting point of ice and the freezing point of water are both 0°C, if the outside temperature is higher than 0°C, then The ice must absorb heat and melt while the ice is kept at 0°C during the melting process. If the outside temperature is lower than 0°C, the water will release heat and then solidify, while the water remains 0°C during the solidification process; The temperature is equal to
