物理化学教学中引导学生深入理解可逆过程的思考

The Experience of Comprehending the Concept of Reversible Process from the Calculation of the Ideal Gas Volume Work in Physical Chemistry Teaching

可逆过程是热力学中非常重要的基础性概念之一。以一定量的理想气体等温膨胀、压缩过程为例子,通过分别计算经过一次膨胀和压缩、两次膨胀和压缩及可逆过程的功使学生深入理解"系统完成一个循环后,系统和环境留都完全复原,没有留下任何影响,这种过程称为可逆过程"这一重要概念。

Reversible process is one of the very important basic concept in thermodynamic.We take the calculation of the work through one time expansion and compression,two times expansion and compression and reversible process of certain amount of gas as example to make the students understanding the very important concept ＂after the system has completed one cycle,the system and the environment to remain completely recovery,did not leave any impact,this process is called reversible process＂.
