It may be interpreted as a measure of the dispersal or distribution of matter and/or energy in a system, and it is often described as representing the “disorder” of the system. For a given substance, Ssolid<Sliquid<Sgas in a given physical state at a given temperature.

In this chapter we introduce the concept of entropy as derived by Rudolf Clausius and formulate the second law of thermodynamics. The second law of thermodynamics is of central importance in science and tells us the direction of spontaneous change for any process. We then calculate the change of entropy for a number of example cases.

It illustrates that as volume increases, temperature decreases, using the ideal gas law to interconnect pressure, volume, and temperature.
