Summary

Chapter 15 presents the two great laws of thermodynamics. The first law applies
conservation of energy to thermodynamic systems. The second law defines the concept of
entropy and the limits on the ability

to use the energy of the system to do useful work.
The chapter concludes with a discussion of practical devices and optional sections on the
application of thermodynamics to current topics.
