类型一:分子热运动扩散现象和分子间作用力是分子运动论的主要内容,多以填空题、选择题的形式进行考查.例1下列现象中,能说明分子做无规则运动的是().A.扫地时尘土飞扬B.气体容易被压缩C.蜡烛“流泪”D.美酒飘香解析A、C选项中的尘土、蜡烛不是分子,属物体的机械运动;B选项说明气体分子间有空隙;D选项说明分子在做无规则运动.应选D.类型二:改变内能的方法改变内能的方法有做功和热传递两种,物体的内能改变与热量、
Type 1: Molecules Thermal kinetic diffusion and intermolecular force are the main contents of molecular motion theory, mostly in the form of blank filling questions, multiple choice questions to examine Example 1 Among the following phenomena, it can be shown that molecules do irregular movements () B. dust swept away B. gas easily be compressed C. candle “tears ” D. wine fragrance analysis A, C options in the dust, the candle is not a molecule, belonging to the mechanical movement of objects; B options that gas molecules There are gaps; D options that do not move the molecule should be selected D. Type II: the method to change the internal energy to change the internal energy There are two kinds of work and heat transfer, the internal energy of the object to change and heat,
