一种新颖的测定分子间势能及普适气体常量R的热学实验装置设计

An Original Design of Calorifics Experiment of Measuring the Value of Intermolecular Interaction Potential and Universal Gas Constant R

设计了一种简单的实验装置,可同时测量分子间相互作用的势能和普适气体常量R。其实验曲线符合理论值,误差分析后的补偿曲线所得结果可较为精确地与理论结果吻合。该实验常温下即可进行,且精度较高。该装置可用于课堂教学,有利于学生对热学问题的深入理解。

We designed an original method of measuring the value of intermolecular interaction potential and universal gas con- stant R with simple instruments at the same time. According to the theory of momentum conservation, and CO2 gas can be seen as Van der Waals gas at room temperature, we design the integrated experiment which can be done at room temperature and can be applied to lecturing. And this can solve the problem of the lack of gas dynamic theory experiment in the college physics class.
