I am not a researcher in thermodynamics. I know that entropy is an extensive status variable which is not defined sufficiently clear (to me). The entropy (usual symbol S) is a “measure of the number of microscopic configurations” that corresponds to a thermodynamic system in a state specified by certain macroscopic variables and entropy is generally used for closed systems. However, the thermodynamics don’t know anything about “microscopic configurations”.
It is true, there are inter molecular order to be connect to intra molecular disorder, but how? Nobody knows at the moments.
