  • To derive relations for specific heats, internal energy, entropy, enthalpy and Joule-Thomson coefficient in standard form

9.1 Introduction

In this chapter, we develop important relations between easily measurable properties of a system and those that are not so easily or directly measurable. It should be noted that temperature, pressure and volume are the properties that are directly measurable. It will be our endeavour to convert the relevant equations into a form that puts the measurable properties on the right-hand side of the equations. During this process, all ...
