Disorder
A state of confusion; a lack of order or regular arrangement; in thermodynamics, a simplified representation of entropy, referring to the randomness or chaotic arrangement of particles in a system.
While often used interchangeably with entropy in casual discussions, 'disorder' is a less precise term. Entropy is a quantitative measure of the number of possible microstates, whereas disorder is a qualitative description of that state.
