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.
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.
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.
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
An increase in rainfall can increase the slope of a stream by eroding the surrounding land and steepening the riverbanks. Conversely, a decrease in rainfall or the deposition of sediment along the streambed can decrease the slope of a stream by smoothing out its gradient.
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, entropy can only increase or remain constant, but it cannot decrease.
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.

If you include the student in the system, the entropy will increase, not decrease.
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.

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.
A process takes place from initiation to completion without an increase or decrease in the entropy
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.
