一、《课程标准》对“熵”的内容的要求“热力学定律与能量守恒”是高中物理《课程标准》中选修模块3-3内容的二级主题,是分子物理学和热学的重要内容.在介绍熵的概念时,它的要求是:通过自然界中宏观过程的方向性,了解热力学第二定律,初步了解熵是反映系统无序程度的物理量.表1 四种版本新教材中“熵”内容的比较 First, the “curriculum standards” “entropy ” content requirements “The laws of thermodynamics and energy conservation ” is a high school physics “curriculum standards” elective module 3-3 content of the second level topics, is the molecular physics and thermal In the introduction of the concept of entropy, its requirements are: through the nature of the macro-process direction, understand the second law of thermodynamics, preliminary understanding of entropy is a reflection of the degree of system disorder physical quantity .Table 1 four versions of the new textbook In the “entropy” content comparison
