Does entropy ever stay the same?
More specifically, the second law of thermodynamics states that “as one goes forward in time, the net entropy (degree of disorder) of any isolated or closed system will always increase (or at least stay the same).” Entropy is simply a measure of disorder and affects all aspects of our daily lives.
Entropy can be thought of as a measure of the dispersal of energy. It measures how much energy has been dispersed in a process. The flow of any energy is always from high to low. Hence, entropy always tends to increase.
If the entropy is constant in either direction of time, there would be no preferred direction. However, the entropy can only be a constant if the system is in the highest possible state of disorder, such as a gas that always was, and always will be, uniformly spread out in its container.
Yes, that's true. But there are two very different reasons why the entropy of a system can change: Because there was dissipation, an irreversible change to the system that turns useful work into wasted heat or. Because the system was open, and entropy was allowed to flow in or out of it.
Following the increase of entropy, the dissipation of matter and energy goes on until our universe becomes so infinitely disordered that entropy can no longer increase and events come to an end. This is called the heat death of the universe.
There is no such maximum limit for Entropy since its most unusable energy and the quality of energy.
Entropy is generated everywhere and always (and thus overall increased), at any scale without exception (including infinitesimal open systems, micro-fluctuations, gravity or entanglement, far-field interactions), but entropy cannot be destroyed by any means, at any scale, and thus, entropy cannot overall decrease (Box ...
A phase change from a liquid to a solid (i.e. freezing), or from a gas to a liquid (i.e. condensation) results in an decrease in the disorder of the substance, and a decrease in the entropy.
Entropy increases when a substance is broken up into multiple parts. The process of dissolution increases entropy because the solute particles become separated from one another when a solution is formed. Entropy increases as temperature increases.
Therefore we state the second law in the following way: The total entropy of the universe is always increasing. When entropy increases, a certain amount of energy becomes permanently unavailable to do useful work.
Will entropy ever be reversed?
It is not possible to reverse entropy in a closed system. Therefore, as changes between events progress, all closed systems over time will tend toward high entropy. Obviously, entropy will decrease because of statistical probability in the very short term, but it is extremely rare.
Entropy is the loss of energy available to do work. Another form of the second law of thermodynamics states that the total entropy of a system either increases or remains constant; it never decreases. Entropy is zero in a reversible process; it increases in an irreversible process.
