物理化学中体积功的计算

摘要

Physical Chemistry is an important basic course of Chemistry, Chemical Engineering, and other special fields. It plays an important role in daily life and scientific studies. The first law of thermodynamics is the basic content of Physical Chemistry. Calculation of volume work is an important step in the application of first law of thermodynamics. According to the formula for calculating volume work, the calculation methods of volume work of several common processes were summarized, including free expansion, isothermal process, adiabatic process, respectively.%物理化学是大学化学化工及其他相关专业的一门重要基础课，在日常生活和科学研究中起着重要的指导作用。热力学第一定律是物理化学的基础内容，而体积功的计算是正确理解和运用热力学第一定律的重要环节。本文阐述了正确理解和运用体积功计算公式应该注意的几个方面，并结合例题总结了常见几种过程如自由膨胀过程，等温过程，绝热过程等过程体积功的计算方法。
