摘　　要：将市售碳酸饮料作为实验对象,通过测试瓶体内CO_(2)气体质量及体积变化,实现瓶内气体压强、气体摩尔体积与温度相关性的实验探究,在有效避免气体实验操作易受干扰、不易定量表观等问题的同时,促进了学生对理想气体状态方程、气体摩尔体积,及勒夏特列定律的深度理解和灵活应用。该实验的原料及仪器准备方便快捷、操作安全且易于观察,既可作为教师的课堂演示实验,亦可作为提升学生学习兴趣和动手能力的家庭实验。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 CO_(2)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.

关 键 词：理想气体状态方程 气体摩尔体积 勒夏特列定律
