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.

Key words: Physical chemistry, Seminar, Bubble experiment, Cultivating students' ability
