CHAPTER 1 INTRODUCTION 1.1 What is thermodynamics? Thermodynamics is the science which has evolved from the original investigations in the 19th century into the nature of “heat.” At the time‚ the leading theory of heat was that it was a type of fluid‚ which could flow from a hot body to a colder one when they were brought into contact. We now know that what was then called “heat” is not a fluid‚ but is actually a form of energy – it is the energy associated with the continual‚ random motion of the
