Yes. Diffusion will increase the entropy.
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.
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.
Processes that result in a decrease in entropy and internal energy typically involve the transfer of energy out of a system, such as in exothermic reactions or phase transitions like freezing. In these cases, the system loses heat to its surroundings, leading to a more ordered state and lower entropy. Additionally, work done on the system, such as compression, can also decrease internal energy and entropy if it results in a more organized arrangement of particles. Overall, these processes favor stability and order at the expense of energy availability.
Entropy would decrease in the process represented by option C: CO2(g) → CO2(l). In this transition, gaseous CO2, which has higher disorder and randomness, condenses into liquid CO2, resulting in a more ordered state and a decrease in entropy. The other options involve processes that either maintain or increase entropy.
Yes. Diffusion will increase the entropy.
Entropy diffusion can lead to an increase in disorder and randomness within a system, which can decrease its overall stability. This is because as entropy increases, the system's energy becomes more dispersed and less organized, making it harder for the system to maintain its structure and function effectively.

Only by increasing the entropy of another system.
For a spontaneous process to occur, the conditions must involve an increase in entropy and a decrease in free energy.

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.

To decrease the entropy of a static body, you would need to decrease the disorder or randomness of its particles. This can be achieved by cooling the body, which can lower the thermal motion of its particles and reduce their entropy. Other methods include applying pressure to order the particles or removing impurities that contribute to disorder.
