There is at least one non spontaneous reactions occuring in the particular system. So someone or something has to shred energy in order to continue the procedure.

What happens to the entropy in the reaction?
Entropy increases. In a reaction comprised of sub-reactions, some sub-reactions may show a decrease in entropy but the entire reaction will show an increase of entropy. As an example, the formation of sugar molecules by living organisms is a process that shows decrease in entropy at the expense of the loss of entropy by the sun.
When salt is dissolved in water do you think the entropy of the system of salt and water increases or decreases?
Entropy will decrease.
How can you decrease the entropy of static body?
You can decrease the entropy of a static body by reducing the temperature.
Does diffusion involve a decrease in entropy?
no.
What the would result in a decrease in entropy?
The meaning is more order.
Is there anyway to decrease the entropy?
Only by increasing the entropy of another system.
When a student cleans their dorm room the entropy of the system must decrease How is this NOT a violation of the second law of thermodynamics?
If you include the student in the system, the entropy will increase, not decrease.
Can you decrease the entropy if yes then how and if not then why?
You cannot reduce entropy because entropy increases (Second Law of Thermodynamics), if you could, we could have perpetual motion. When work is achieved energy is lost to heat. The only way to decrease the entropy of a system is to increase the entropy of another system.

Is it true that the entropy of a system decreases over time?
false

Entropy will decrease.
Under what condition can entropy decrease in a system?
First of all, entropy is the defined as the extent to which something is disordered. In chemistry, for entropy in a SYSTEM to decrease, the products of a reaction must be less disordered than the reactants. The extent of "disordered-ness" can be seen by the physical states of the substances. A gas is more disordered than a liquid, which is more disordered than a solid. So, an example of a reaction that leads to a decrease in entropy is: HCl(gas) +NH3(gas) -----> NH4Cl(solid) So you see, there are more gaseous molecules in the reactant side of the equation than in the product side, which means the products are less disordered than the reactants. ----------------------------------------------- However, one must note that if the entropy of a system(reaction) decreases, the entropy of the surroundings should increase. This is because change in TOTAL entropy(A) = change in entropy of SYSTEM(B) + change in entropy of SURROUNDINGS(C). It is a rule that A must increase in every case ( have a positive value). If the B is negative(a decrease in entropy), C must be positive(an increase in entropy) to keep the value of A positive.
How can you decrease the entropy of static body?
You can decrease the entropy of a static body by reducing the temperature.
Is a statement of the second law of thermodynamics?
An isolated system tend to equilibrium and entropy cannot decrease.
According to the second law of thermodynamics does entropy increase in a cold system?
That depends on what you mean by "cold" system. Entropy in any system can do one of three things: increase, decrease, or remain constant. If the system is closed, then entropy will only ever increase. If the system is open, entropy within it can do any of the three, provided there is a corresponding change in entropy outside the system (energy must come from or go to somewhere to effect an entropy change). The absolute amount of energy in the system makes no difference to the entropy of it. It is whether you have an open or closed system that counts.
Does diffusion involve a decrease in entropy?
no.
What results in decrease in entropy?
Water Freezing
