一、情境描述“探究气体体积的规律”是高中化学第一册第二章第二节内容,它是本章及本册乃至整个高中化学的重要内容,是在学习了物质的量的基础上学习气体摩尔体积,为以后学习有关气态反应物和生成物的化学方程式计算以及化学反应速率、化学平衡必备的基础知识。本节课内容之前学生已经学习了物质的量,掌握了物质的量与微粒个数之间的关系,虽然没有气体摩尔体积的概念,但他们具有微粒运动的基本知识和一定的逻辑推理能力。
I. Contextual Description “The law of gas volume” is the second volume of Chapter 2 of the first volume of high school chemistry. It is an important part of the chemistry of this chapter and the whole high school. It is based on the study of the amount of matter Learn the molar volume of gas to learn the basics of the chemical equations necessary to calculate chemical reactants and chemical reactions for later chemical reactants and products. Before this lesson, students learned about the amount of matter and mastered the relationship between the amount of matter and the number of particles. Although there is no concept of gas molar volume, they have the basic knowledge of particle motions and some logical reasoning ability.
