... Entropy is the heat added (or subtracted), ΔQ, to a system divided by its temperature in Kelvin (T). It is a measure of the disorder of a system; a measure of the unavailability of a system’s energy to do work; a measure of the disorder of the molecules in a system; a measure of the number of possib ...
