Abstract

Abstract:

At present, the definition of isothermal process and heat in textbooks of physical chemistry make students confused when investigating heat transfer of the isothermal process. Isolated and incomplete understanding of concepts are the fundamental causes of the result. In order to clear the learning barrier for the beginner of physical chemistry, by taking isothermal reversible expansion process of perfect gas as an example, the heat transfer of isothermal process was explained in detail, and the mathematical limit thought was used in analysis process in the article.

Key words: Perfect gas, Isothermal process, Heat, Work
