Thermodynamics of a Pure Substance



The main purpose of this chapter is to briefly recapitulate what is learned in a first course in classical thermodynamics (Only those portions of a typical undergraduate curriculum that are relevant to combustion calculations are given emphasis). As defined in Chap.  1, thermodynamics is the science of relationships among heat, work, and the properties of the system. Our first task, therefore, will be to define the keywords in this definition: system, heat, work, and properties. The relationships among these quantities are embodied in the First and the Second laws of thermodynamics. The laws enable one to evaluate the change in the states of the system, as identified by the changes in its properties. In thermodynamics, this change is called a process, although, in common everyday language, the processes maybe identified with terms such as cooling, heating, expansion, compression, phase change (melting, solidification, evaporation, condensation), or chemical reaction (such as combustion, catalysis, etc.). As such, it is important to define two additional terms: state and process.
