What else can I help you with?
When water becomes ice the entropy decreases does this contradict the second law?
No, because the entropy of the surroundings must increase more than the decrease in the water->ice transition, thus the net change in the entropy of the universe is positive, consistent with the second law.
Does diffusion involve a decrease in entropy?
no.
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.
What equation will cause entropy to decrease apex?
Entropy, a measure of disorder in a system, typically increases according to the second law of thermodynamics. However, entropy can decrease in a localized system when energy is added or work is done on the system, as described by the equation ΔS = Q/T, where ΔS is the change in entropy, Q is the heat added, and T is the temperature. For example, in refrigeration cycles, work is done to remove heat from a cold reservoir, decreasing its entropy at the expense of increasing the entropy of the surroundings. Thus, while entropy can decrease locally, the overall entropy of the universe still increases.
What would decrease in entropy apex?
A decrease in entropy typically occurs in processes that involve the organization of matter or energy, such as the formation of ice from water or the crystallization of a substance from a solution. In these cases, particles become more ordered, resulting in a lower entropy state. Additionally, when energy is added to a system in a controlled manner, such as cooling a gas, it can lead to reduced disorder and lower entropy. However, according to the second law of thermodynamics, the total entropy of an isolated system can never decrease; it can only decrease locally at the expense of increasing the overall entropy elsewhere.
Is there anyway to decrease the entropy?
Only by increasing the entropy of another system.

What would happen to the entropy in the reaction 2O3 g 3O2 g?
It increases
What result in a decrease in entropy?
water freezing
What results in decrease in entropy?
Water Freezing
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.
What happens to entropy when energy is transformed?
When energy is transformed, entropy can either increase or decrease. For example, in many energy transformations, such as combustion or chemical reactions, entropy tends to increase due to the dispersal of energy. However, in some processes, such as certain phase changes, entropy can decrease.
Would result in a decrease in entropy?
water freezing
When you straighten up your work space do you increase or decrease the entropy of your work space?
decrease
