论文部分内容阅读
对分子动理论部分的内容,知识要求是理解分子动理论的三个方面的内容,即物质是由大量分子组成的;分子在永不停息地做无规则的热运动;分子间存在着相互作用的引力和斥力。能力要求是使同学们能够在初中对分子动理论内容定性认识的基础上提高到定量认识.方法要求是实验探索、理论计算、实际分析.那么,如何突破分子运动论的重点问题呢:一、关于阿伏加德罗常数的计算问题的突破原则1.明确各物理量的具体含义及它们之间的相互关系经常出现的物理量有:质量 m、体积 V、摩尔质量
For the part of the theory of molecular dynamics, the knowledge requirement is the content of understanding the three aspects of molecular dynamic theory, that is, the material is composed of a large number of molecules; the molecules never cease to do irregular heat movement; there is an interaction between molecules. Gravity and repulsion. The ability requirement is to enable the students to improve the quantitative understanding based on the qualitative knowledge of the molecular dynamic theory in the junior middle school. The method requirements are experimental exploration, theoretical calculation, and practical analysis. So, how to break through the key issues of molecular movement theory? Breakthrough Principles for the Calculation of Avogadro’s Constant 1. Identify the specific meanings of each physical quantity and the relationships between them The physical quantities that often appear are: mass m, volume V, molar mass
