Entropy is the tendency of the universe to become more disorganized. Photosynthesis decreases entropy because it takes a larger number of reactants and converts them into a more organized form of energy, where there are less products than reactants.
6 H2O + 6 CO2 ---> C6H12O6 + 6 O2

When water becomes ice the entropy decreases does this contradict the second law?
No, the decrease in entropy of water turning into ice does not violate the second law of thermodynamics. The second law states that the total entropy of an isolated system can never decrease, but entropy can decrease locally within the system as long as there is a corresponding increase in entropy elsewhere. In the case of water turning into ice, the decrease in entropy of the water molecules is offset by an increase in entropy in the surroundings.
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.
Did the snows entropy increase or decrease while in your hand?
The snow's entropy likely increased while in my hand. As it melts and changes state from a solid to a liquid, the disorder and randomness of its molecules increase, leading to an increase in entropy.
How can the net amount of entropy of the universe be massively decreased?
The net amount of entropy in the universe can only decrease if there is a localized decrease in entropy, which requires a larger increase in entropy in the surrounding environment to comply with the second law of thermodynamics. This is a highly unlikely scenario on a cosmic scale, as the overall trend in the universe is towards increased entropy.
Does diffusion increase the entropy of a solution?
Yes. Diffusion will increase the entropy.
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.

When you straighten up your work space do you increase or decrease the entropy of your work space?
decrease
Did the ice's entropy increase or decrease over time?
increased
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?
Entropy is a measure of disorder or randomness in a system, and it tends to increase over time due to natural processes. It is not typically possible to decrease entropy in a closed system without external intervention, as this would go against the natural direction of increasing disorder. However, in specific cases, energy can be input to decrease entropy locally, but this overall requires an increase in entropy in the larger system.

What is isentropic?
A process takes place from initiation to completion without an increase or decrease in the entropy
When disorder in a system increases does entropy increase or decrease?
When disorder in a system increases, entropy increases. Entropy is a measure of the randomness or disorder in a system, so as disorder increases, the entropy of the system also increases.
Is it true that the entropy of a system decreases over time?
false
Does entropy increase or decrease due to friction?
Entropy increases due to friction. Friction generates heat, which increases the overall disorder or randomness of the system, leading to an increase in entropy.
