Entropy
Entropy is a measure of the lack of order or predictability within a system, quantifying the degree to which the components of the system are arranged randomly or chaotically. It represents the natural tendency for systems to undergo a gradual decline into disorder, reflecting the increase in uncertainty and the reduction of usable energy available to do work.
In essence, higher entropy indicates a higher level of disorder and less predictability, while lower entropy signifies more organised and predictable states.
