分子动理论是从物质微观结构的观点来研究热现象的理论.它的基本内容是:物体是由大量分子组成的;分子永不停息地做无规则运动;分子间存在着相互作用力.学习分子动理论有以下几个要点应掌握.一、抓住阿伏加德罗常数的桥梁作用物体是由大量分子组成的.这里的分子是指构成物质的单元,可以是原子、离子,也可以是分子.可把分子看做小球,所 The theory of molecular mobility is a theory that studies the phenomenon of thermal phenomena from the perspective of the material microstructure. Its basic content is that objects are made up of a large number of molecules, that molecules exercise no rules of motion, and that there is interaction between molecules. Molecular dynamics theory has the following points should be mastered. First, to capture the role of the bridge Avogadro’s object is composed of a large number of molecules. Here refers to the composition of the material unit, which can be atoms, ions, It is a molecule, a molecule can be seen as a sphere
