《中学教材全解.高中物理.选修3-3》(陕西人民教育出版社),关于分子平均动能有如下注释:“同一温度下,不同物质(如铁、铜、水、木……)的分子平均动能都相同,但由于不同物质分子的质量不尽相同,所以分子运动的平均速度大小不尽相同.”对于这一注释,笔者不敢苟同.关于温度相同的 “High School Physics Textbook Solution, High School Physics, Elective 3-3” (Shaanxi People’s Education Press), with the following comment on the average molecular kinetic energy: “At the same temperature, different materials (such as iron, copper, water, wood...) The average kinetic energy of molecules is the same, but because the mass of different material molecules is not the same, the average speed of molecular motion is not the same.” For this comment, the author does not dare to agree on the same temperature.
