以前曾看到几份初中物理辅导材料 ,其中汽化部分内容均有这样的题目 :判断“蒸发需吸热”说法的正误材料给出的“正确”答案均是“蒸发需吸热” .有的老师在总结汽化的两种形式———蒸发、沸腾的相同点时说“都吸热” .还有的老师在总结蒸发特点时就说 ,“蒸发需吸热” .有的 In the past, I have seen several junior high school physics guidance materials, some of which have the following topics: The “correct” answers given in the judgment of “evaporation requires heat absorption” are “evaporation requires heat absorption”. When the teacher summarized the two forms of vaporization—the same point of evaporation and boiling, he said “all absorb heat.” Other teachers said when summing up the characteristics of evaporation, “evaporation requires heat absorption.”
