摘要:

普适气体常量R是物理学中的一个重要常数,也是贯穿普通化学教学的一个基本常数。文中介绍了普适气体常量的由来、数值测定、物理意义及在普化教育中的应用,同时对不同公式中R的取值进行了归纳和总结,旨在为非化学专业理工学生补充关于R的知识,帮助学生更好地学习和掌握普通化学的基本原理。

关键词: 普适气体常量, 玻尔兹曼常数, 声学测量方法

Abstract:

The universal gas constant R is an important constant in physics, and one of the vital fundamental constant throughout the teaching of general chemistry. This article aims to present a general review about the universal gas constant to the science and engineering majored students, including its history, determination, physical meaning and applications in chemical education. The choice of R values under various conditions is also provided to help students better understand and master basic concepts.

Key words: Universal gas constant, Boltzmann's constant, Acoustic measurement
