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 can decrease in a reaction when a system transitions from a more disordered state to a more ordered state, often observed in processes like crystallization or the formation of complex molecules from simpler ones. This decrease typically occurs in a local context, as the overall entropy of the universe still tends to increase according to the second law of thermodynamics. Additionally, external energy input can drive reactions that lead to a decrease in entropy within a system. However, it’s important to remember that while entropy may decrease locally, the total entropy of the combined system and surroundings will increase.
Entropy is the scientific concept of disorder and randomness that has many broad applications across different branches of physics. While it is not a law itself, it is central to understanding the Second Law of Thermodynamics, as objects that are in thermodynamic equilibrium are at their highest state of entropy.
The formation of frost on a window pane represents a decrease in entropy, as it involves the transition from a more disordered gaseous state (water vapor) to a more ordered solid state (ice crystals). This process is exothermic and releases heat, contributing to the overall entropy change of the system. While the local entropy decreases, the total entropy of the universe still increases due to the heat released into the surroundings. Thus, the local entropy change is negative, but the overall entropy of the universe increases.
In the reaction 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(l), the entropy decreases. This is because the reactants consist of gaseous molecules, which have higher entropy due to their greater freedom of movement, while the products include liquid water, which has lower entropy. Additionally, there is a reduction in the number of gas molecules from 7 (2 C2H2 + 5 O2) to 4 (4 CO2), further contributing to the decrease in disorder. Overall, the transition from gas to liquid and the reduction in the number of gas molecules results in a net decrease in entropy.
No, temperatures generally decrease as latitudes increase. The equator (30° to 40°C) is 0° latitude while the poles (0° to -40°C) are at 90° latitude.

Entropy is a measure of disorder in a system, and according to the second law of thermodynamics, entropy tends to increase over time. While it is theoretically possible to temporarily decrease entropy in a localized system, reversing entropy on a large scale is not feasible based on our current understanding of physics.
The reason that entropy increases is related to statistics. It is possible in theory that a process occurs in such a way that entropy decreases, but this is so unlikely that it will never happen in practice.
The amount of randomness in the system
if there is an increase in the number of gas molecules , then ^S > 0
The system becomes more random.
Increase
Entropy is a measure of disorder or randomness in a system, while energy is the capacity to do work. The relationship between entropy and energy is that as energy is transferred or transformed in a system, the entropy of that system tends to increase. This is known as the second law of thermodynamics, which states that in any energy transfer or transformation, the total entropy of a closed system will always increase over time.
Increase
An increase in temperature will cause an increase in volume, while a decrease in temperature will cause a decrease in volume.
In a chemical system, exothermic reactions release heat energy, while entropy changes refer to the disorder or randomness of molecules. Exothermic reactions typically lead to an increase in entropy, as the released heat energy can increase the movement and randomness of molecules in the system.
