Entropy
Entropy is a measure of disorder or randomness in a system. In thermodynamics, it helps us understand how energy is distributed and transformed. When a system moves towards equilibrium, its entropy increases, indicating that energy is spreading out and becoming less concentrated. Essentially, higher entropy means a system is more disordered and less capable of doing useful work. For example, when ice melts into water, the ordered arrangement of ice molecules becomes more random, resulting in increased entropy. Thus, entropy provides insight into the direction of natural processes and the efficiency of energy use.

Entropy is a concept from thermodynamics and information theory that measures disorder or randomness in a system. In everyday terms, think of entropy as a gauge of chaos: the higher the entropy, the more disordered or spread out the energy or information is. For example, a room that’s cluttered with items has high entropy, while a neatly organized room has low entropy. In nature, systems tend to progress towards higher entropy, meaning they drift towards disorder over time. This tendency is fundamental in understanding processes like the direction of heat flow and the evolution of complex systems.
