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
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.
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?
Increase. The heat from your hand will melt the snow causing it to go from a low entropy solid state to a higher entropy liquid state.
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.
In an isolated system, can entropy only increase?
In an isolated system, entropy can only increase or remain constant, but it cannot decrease.
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.
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?
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 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?
Increase. The heat from your hand will melt the snow causing it to go from a low entropy solid state to a higher entropy liquid state.
Is entropy always conserved in a closed system?
No, entropy is not always conserved in a closed system. Entropy can increase or decrease in a closed system depending on the processes happening within it.
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.
