Abstract Using carbonated beverages as experimental objects, the correlation between the pressure, molar volume and temperature of the gas in the bottle is calculated by testing the mass and volume of CO2 gas inside the bottle, which not only effectively avoids the problems of interference and difficulty in visualization of gas experiments, but also promotes students’ in-depth understanding and flexible application of the ideal gas equation of state, the molar volume of gases, and Le Chatelier’s law. The raw materials and instruments of this experiment come from daily life, so it is easy to prepare, safe to operate and easy to observe. It can be used as a classroom demonstration experiment for teachers, or as a home experiment to enhance students’ interest in learning and hands-on ability.
