Thermodynamic entropy is a non-conserved state function that is of great
importance in the sciences of physics and chemistry. Historically, the concept of entropy evolved
in order to explain why some processes (permitted by conservation laws) occur spontaneously
while their time reversals (also permitted by conservation laws) do not; systems tend to progress
in the direction of increasing entropy. For isolated systems, entropy never decreases. This fact
has several important consequences in science: first, it prohibits \"perpetual motion\" machines;
and second, it implies the arrow of entropy has the same directionality as the arrow of time.
Increases in entropy correspond to irreversible changes in a system, because some energy is
expended as waste heat, limiting the amount of work a system can do. In statistical mechanics,
entropy is a measure of the number of ways in which a system may be arranged, often taken to
be a measure of \"disorder\" (the higher the entropy, the higher the disorder). This definition
describes the entropy as being proportional to the natural logarithm of the number of possible
microscopic configurations of the individual atoms and molecules of the system (microstates)
which could give rise to the observed macroscopic state (macrostate) of the system. The constant
of proportionality is the Boltzmann constant. - Wiki
