Answer» tion:In statistical mechanics, entropy is an EXTENSIVE property of a thermodynamic SYSTEM. It is closely related to the number Ωof microscopic configurations (known as microstates) that are consistent with the macroscopic QUANTITIES that characterize the system (such as its volume, pressure and temperature). Under the assumption that each microstate is EQUALLY probable, the entropy {\displaystyle S}is the natural logarithm of the number of microstates, multiplied by the Boltzmann constant kB. FORMALLY (assuming equiprobable microstates),
