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

What is a sample that has greater entropy?
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.
What does the relay do in a compressor?
the relay in the compressor helps it to respond to pressure increase or decrease process in relation to a gas.
Entropy is the measure of the amount of disorder in a system?
true
Which process will lead to larger work output isothermal process or polytropic process with n1.25?
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.
Is the expansion of superheated steam isothermal?
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
What is isentropic process?
A process takes place from initiation to completion without an increase or decrease in the entropy
What happens to the entropy in the reaction?
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.
What is isentropic?
A process takes place from initiation to completion without an increase or decrease in the entropy
How can you decrease the entropy of static body?
You can decrease the entropy of a static body by reducing the temperature.
Is there anyway to decrease the entropy?
Only by increasing the entropy of another system.
The favorability or spontaneity of a reaction increases when during the course of a reaction?
the energy content and entropy both decrease
Does diffusion involve a decrease in entropy?
no.
Can you decrease the entropy if yes then how and if not then why?
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.
What must happen to the entropy of the universe during a spontaneous reaction or process?
It increases.
What results in decrease in entropy?
Water Freezing
What result in a decrease in entropy?
water freezing
Where an decrease in thermal energy is occurring?
entropy
