One of the principal objectives of this chapter is to see how various
thermodynamic properties relate to one another, expressed 1. by an equation of
state, 2. by a calorific equation of state, and 3. by temperature–entropy, or
Gibbs, relationships. Before we do that, however, we list in Table 2.1 the most
common properties so that you might have an overview of the scope of our
study. You may be familiar with many of these properties, although others will
be new and may seem strange. As we proceed in our study, this strangeness
should disappear as you work with these new properties. We begin with a
discussion of three extensive properties: mass, number of moles, and volume.
