物理化学热力学计算和实验研究

Study on Caculation and Experiment of Thermodynamics in Physical Chemistry

《物理化学》热力学部分是课程的重要章节,本文比较了热力学部分理想气体绝热可逆过程方程式和理想气体单纯PVT变化熵变计算公式的相似性,并提出一种记忆方法-六格子法,有助于帮助学生和教师轻松记住热力学部分的六个计算公式。随后,举例说明理想气体绝热可逆过程方程式和理想气体单纯PVT变化熵变计算公式的应用,为学生的热力学学习增添了乐趣,提高了学生的学习兴趣,有助于学生更好掌握和利用公式去解决实际问题,进一步培养学生对物理化学其他公式归纳总结的能力,从而进一步锻炼学生发现问题、思考问题、分析问题、解决问题、总结问题的能力乃至创新能力等。

The thermodynamic part of physical chemistry is an important part of the course.It is comparedthat the similarity between the adiabatic reversible process equation of ideal gas and the entropy change calculation formula of pure PVT change of ideal gas in this paper.And a memory method-six grids method is put forward.It is helpful for students and teachers to easily remember the six calculation formulas of thermodynamics.Then,examples are given to illustrate the application of ideal gas adiabatic reversible process equation and ideal gas simple PVT change entropy change calculation formula,which adds fun to students'thermodynamic learning,improves students'interest in learning,helps students better master and use formulas to solve practical problems,and further cultivate students'ability to summarize other formulas in physical chemistry,so as to further train students'ability to find problems,think about problems,analyze problems,solve problems,summarize problems and even innovate.
