Entropy, like temperature and pressure, can be explained on both a macro scale and a micro scale. Since thermodynamics deals only with the macro scale, the change in entropy delta S is defined here to be the heat transfer delta ... Substituting these forms for dQ into the differential form of the entropy equation gives::

Thematic, scientific definitions of entropy ... In equation 1, S is the entropy, Q is the heat content of the system, and T is the temperature of the system. At this time, the idea of a gas being made up of tiny molecules, and temperature representing their average kinetic energy, had not yet appeared.

The microscopic explanation of entropy has never been fully accepted1-3 since there is incomplete proof for equation 2 and there are counter examples where the increase of disorder cannot be justified. ... This equation contains the expression of entropy for constant volume. ... Substituting entropy into equation 17 gives...

If there is no heat transfer, the change of entropy is zero and we have a process that is reversible. The equation derived above relates the change in temperature to the change in pressure. For a given compression ratio, we can determine how hot the gas becomes.

Boltzmann's entropy equation talks about a specific kind of system--an isolated system with a specified constant total energy E (although the constant E does not explicitly appear in the equation, it is implied and crucial) in a state of equilibrium.
