Which term means a lack of order or predictability; a gradual decline into disorder?

• A. A lack of order or predictability; a gradual decline into disorder
• B. A sudden burst of energy
• C. A measure of randomness in a system
• D. A state of complete calm

Answer: (A)

Entropy captures a lack of order or predictability and the tendency for systems to move toward disorder. In thermodynamics, it measures how energy becomes spread out among all possible configurations; higher entropy means more disorder and less certainty about the exact state. The description given matches this idea: a gradual progression into disorder reflects how entropy increases over time in isolated systems. The other options describe bursts of energy, calm, or a general sense of randomness, but they don’t convey the directional drift toward disorder that entropy embodies. So the term described is entropy.
