人教版高中化学第一册第三章“气体摩尔体积”一节理论性较强 ,比较抽象。例如 ,学生对在相同条件下 ,相同的物质的量的固体、液体的体积不相等还可以理解 ,但对气体的体积相等不太理解。因为课本上也没有通过实验论证过 ,也不好比较。那么怎么设计实验让学生便于直接感到在相
The chapter “Gas Molar Volume” in Chapter 3 of the PEP Chemistry Book 1 is highly theoretical and abstract. For example, students can understand the same volume of solids and liquids under the same conditions, but they do not understand the volume of gas equally. Because textbooks have not been demonstrated through experiments, it is not a good comparison. So how do you design experiments so that students can easily feel in
