SUMMARY
Entropy is quantitatively defined as the measure of the number of specific arrangements of a system, expressed in units of joules per kelvin (J/K). This unit reflects the relationship between energy and temperature, specifically the heat transferred into a system at absolute temperature (in Kelvin). The interpretation of entropy as "disorder" is misleading; instead, it is fundamentally linked to the second law of thermodynamics, which governs the behavior of energy and heat transfer in thermodynamic systems.
