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.

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
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.

You can decrease the entropy of a static body by reducing the temperature.
Only by increasing the entropy of another system.
the energy content and entropy both decrease
no.
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.
It increases.
