in general entropy will not decrease in a spontaneous process since spontaneous process are all irreversible ones. entropy can be reversed only through an reversible process by an ideal engine but it is impossible to create such an engine by violating second law of thermodynamics. hence entropy cannot be decreased practically
A Carnot cycle is a sample of something that has greater entropy. The word entropy can e defined s meaning reverse system. The concept of entropy was started with the work of Lazare Carnot.
the relay in the compressor helps it to respond to pressure increase or decrease process in relation to a gas.
true
The process equation for this is PV up to the nth power which equals C. The polytrophic process is 1.25 which is the n in the equation.
Expansion of steam in either the saturated or superheated state is generally not isothermal. When steam expands from a high pressure to a lower pressure the temperature will be reduced, unless energy is added during the process. When steam expands in an engine such as a steam turbine, the temperature reduction is greater than during free expansion
The entropy of the universe must increase during a spontaneous reaction or process. This is in accordance with the Second Law of Thermodynamics, which states that the total entropy of an isolated system can never decrease over time.
A process takes place from initiation to completion without an increase or decrease in the entropy
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.

Only by increasing the entropy of another system.
no.
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.
For a spontaneous process to occur, the conditions must involve an increase in entropy and a decrease in free energy.
Please be aware that the change will be neither positive or negative. You see when "water" freezes the entropy will not change due the tempertaure of the area around it meaning the entropy will stay neutral. You are very welcome young man
It increases
