ABSTRACT
It is clear that events happen spaced in time, and hence, dynamic modeling is a way to gauge the time scales for different phenomena. Dynamic modeling is a wellestablished art, with many contributions from all over the world at many different times. For an excellent treatment of the topic, the reader may consult Reference 1. We focus here on some simple aspects for modeling most thermal systems at an elementary level. Issues dealing with the nature of time, simultaneity, and entropy generation are well beyond our scope.
