摘要:

化学的核心是基于原子分子的图像认识世界、创造物质,化学教育需要培养学生掌握相应的思维方式。在物理化学类课程建设中,浙江大学化学系尝试把宏观化学的基本理论框架,即热力学理论建立在原子分子水平上。具体地是先简述量子化学对单个原子、分子能级结构的处理,然后利用统计热力学的基本原理,从这些量子化的能级导出宏观系统的三个基石性概念(能量、熵、温度)和一条基本定律(熵增加原理),从而建立分子图像的热力学。在教学实践中,强调直接从原子分子层面切入、弱化热机理论、理论与实验结果直接关联。在本文中,我们通过几个教学实例来分享我们的教学经验。

Abstract:

This in-class teaching design will facilitate students' understanding of how the basic principles and methods of physical chemistry thermodynamics are used to analyze and correct the literature data calculation process in the field of adsorption. Similarly, it will enhance the accuracy and systematicness of students' knowledge of thermodynamics, as well as promote students' interest and self-confidence in learning by employing such a creative and dynamic classroom teaching model of physical chemistry.

Key words: Physical chemistry, Thermodynamics, Statistical thermodynamics
