新制订的《普通高中物理课程标准》在“热现象与规律”的内容中提出“通过自然界中热传导的方向性等事例,初步了解热力学第二定律,初步了解熵是描述系统无序程度的物理量”,将热力学第二定律以及熵的概念首次引入高中物理课堂.本文就谈谈与我们的生活息息相关的熵. 1 熵、熵增加原理 熵这个概念源于热力学.在热力学系统中,有许多
The newly formulated “Standards for Physical Curriculum for Senior Secondary Students” puts forward “Directions of heat conduction in nature, examples of directionality in thermal phenomena” and preliminary understanding of the second law of thermodynamics. A preliminary understanding of entropy is the physical quantity describing the disorder of the system. “The second law of thermodynamics and the concept of entropy are first introduced into the high school physics class. This article will talk about the entropy that is closely related to our lives. 1 Entropy, entropy increase The concept of entropy is derived from thermodynamics. There are many in thermodynamic systems.”
