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.

Can entropy decrease during a process?
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
Entropy is the measure of the amount of disorder in a system?
true
Which has a greater torque a perpendicular force applied at the end of a wrench handle or an equal force applied in the same direction near the middle of the handle?
the perpendicular force applied at the end of a wrench handle. Because torque= Fd / T = F d cos θ therefore the greater the distance the greater the torque. T=torque F=force d=distance cos=cosine θ=theta
What is the larger of the two mating gears?
The gear with the greater number of teeth; it will have a lower angular velocity .
Is the resistance in the start winding greater or less than the resistance in the run winding?
The resistance in the start winding is greater because it is longer and thinner and has the greatest resistance to current flow
Describe the conditions necessary for a sample to have zero entropy?
The only way to have zero entropy is to have a temperature of absolute zero.
Is greater than the entropy of a liquid?
gas
Why does the entropy of water increase as it warms from 0 degrees to 4 degrees?
Heat (in water) is random molecular motion, so greater heat equals greater disorder, hence more entropy.
Can entropy effect osmosis?
In a nutshell, yes. The water will go from a higher concentration to a lower concentration to increase the entropy of the lower concentration area. The increase in entropy of the lower concentration area would be greater than the loss of entropy of the higher concentration giving you a NET increase in total entropy.
Is entropy is greater at higher trophic level than a lower level?
False
Which has a higher entropy a hot water or a cold water?
Entropy is the measure of disorderness. Hot water --> more energy --> less stable --> more disorderness (than Cold water). Therefore, Entropy of Hot water is greater than that of Cold water.
When someone order something don't he reduce entropy of the universe?
No. You can reduce the entropy of some system, but that will be at the cost of an entropy increase somewhere else. This is because it costs energy to put something in order. The TOTAL entropy in the Universe will always increase. For example, the entropy on planet Earth probably remains more or less constant over millions of years - but we do so using energy, mainly from the Sun, and the fact that energy from the Sun radiates into space is an increase of entropy; much greater than any small change of entropy on our planet.
What is the scientific measure of disorder is called?
This is called entropy.
How is a boiled egg in a higher state of disorder than an unboiled egg?
Boiled egg is due to absorption of heat and heat supplied to a system always results in increase in ''Entropy'' Increased Entropy means greater disorder.
One mole of ice at 273 k or one mole of water at the same temperature which one have greater entropy and why?
The water has more entropy, because its atomic structure is less ordered than the atomic structure of the ice.
Which of the following has greater entropy bromine vapor or liquid bromine Iodine vapor or solid iodine Justify your answer.?
Vapors always have more entropy than liquids of the same substance at the same temperature, because the number of energy states accessible to molecules in the vapor phase is much greater than in the liquid phase.
What is true about entropy?
Entropy is not change. Entropy is disorder.
