Statements that best defines entropy

Entropy is a measure of disorder or randomness in a system, reflecting the number of possible arrangements of its components. In thermodynamics, it quantifies the energy in a system that is not available to do work, signifying the irreversibility of natural processes. Higher entropy indicates a greater degree of disorder and energy dispersion, while lower entropy suggests more ordered states. In information theory, entropy quantifies the uncertainty or information content associated with a random variable.
