Physical chemistry is a subject that uses physical phenomena as an entry point to explore chemical reaction processes.Its subject content is profound and abstract,and its difficulty is relatively obvious.There is a relative lack of research and related teaching tools on teaching students how to learn physical chemistry.This study designed a new physical chemistry teaching tool,the first law of thermodynamics flow chart suitable for simple physical change processes.This flow chart provides a systematic method for undergraduates to learn thermodynamics knowledge and effectively improves students'ability to convert between written and mathematical expressions.At the same time,this flow chart provides young teachers with a clear and flexible new teaching framework,allowing young teachers to plan,organize,and carry out classroom teaching more easily,and promotes the innovation and development of physical chemistry education.
