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 else can I help you with?
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 must happen to the entropy of the universe during a spontaneous reaction or process?
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.
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
Is there anyway to decrease the entropy?
Only by increasing the entropy of another system.
Does diffusion involve a decrease in entropy?
no.
When water becomes ice the entropy decreases does this contradict the second law?
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.
What conditions must be met for a spontaneous process to occur?
For a spontaneous process to occur, the conditions must involve an increase in entropy and a decrease in free energy.
When water freezes should the change in entropy be positive or negative and explain?
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
What would happen to the entropy in the reaction 2O3 g 3O2 g?
It increases
What results in decrease in entropy?
Water Freezing
What result in a decrease in entropy?
water freezing
