热力学是物理化学的基础和重要组成部分,但热力学理论性强,概念抽象,公式繁多,推导过程复杂,教学难度和学习难度都很大。详细描述了热力学一些基本理论的教学实践,包括饱和蒸汽压与分压的关系、状态函数和过程量的特点、体积功的计算公式、热力学能和焓变的计算、熵的定义和熵增加原理等热力学中的难点重点。此外阐述了如何利用各种方法和手段,如形象直观的图形、生动活泼的范例和简洁有效的讲解让学生能更加轻松地理解和应用这些知识点。

As the basis and important part of physical chemistry, thermodynamics is characteristic of complex con- tent, abstract concept and complicated formula deduction. In this paper, practice and thinking about some difficult but important knowledge of thermodynamics were proposed, including the relationship between saturated vapor pres- sure and partial pressure, the characteristic of state function and process variability, calculation for the volume work, variation of thermodynamic energy and enthalpy, the definition of entropy and principle of entropy increase. This paper also demonstrates how to employ various methods, such as impressive figures, lively examples and sim- ple statements, to enable students to understand and apply the knowledge more easily.
