摘　　要：在物理化学的"界面与胶体化学"部分,表面张力、表面自由能和拉普拉斯公式是非常基础的内容,如何让学生深刻理解、灵活掌握至为重要,也是该章后续学习的关键。本文以分析两个连通气泡的变化为例,结合演示实验,实施研讨式教学,通过多角度(力学、能量等)、多层次(变化的方向、变化的限度)分析,巩固学生对表面张力、表面自由能及拉普拉斯公式的理解,进而与两个连通气球的变化进行类比,分析两个体系的异同点。通过启发引导,培养学生运用知识、分析问题的能力,提高学生综合素质。在物理化学课堂中,以学生为中心实施基于问题的研讨式教学,为相关课程的教学提供了参考。In the physical chemistry course, surface tension, surface free energy, and Young-Laplace equation are the basics in interface and colloidal chemistry. For students, it is the key to understand the above mentioned content for studying the follow-up knowledge. This paper presented the physical chemistry seminar via exploring the changes of two connected bubbles with different sizes. The demonstration experiments were valuable for students to know better surface tension, surface free energy, and Young-Laplace equation. Cultivating students’ research abilities to apply knowledge and analyze problems were also based on discussing the similarities and differences between two connected balloon and two connected bubbles. The problem-based seminar on physical chemistry could be significant for the related courses.
