The term for the measure of disorder in a system is known as entropy. In thermodynamics, entropy quantifies the level of randomness or chaos associated with a system’s energy distribution. Higher entropy indicates a greater state of disorder, while lower entropy signifies more ordered systems. This concept is integral to the second law of thermodynamics, which states that entropy in a closed system tends to increase over time. Understanding entropy has important implications in fields such as physics, chemistry, and information theory, contributing to our comprehension of natural processes.
