System A in Surroundings I is placed in Surroundings II. What will happen?

This chapter supplies answers to that question for the simplest class of

thermodynamic system: a unary, homogeneous, closed, nonreacting, otherwise

simple system. A part of the answer to the question, “What will happen?” is the more

specific question, “What changes will occur in its properties?” Strategies for

computing thermodynamic properties, referred to in Figure 1.4, begin with methods

developed for such simple systems.
