Explanation:

Of phases, from greatest to least entropy is gas>liquid>solid. Dissolve a salt right into solution is boost in entropy because the salt has actually greater an are to move. The only decrease in entropy is condensation that water ~ above glass (gas to liquid)


Explanation:

Entropy for phases room Gas>Liquid>Solid. A salt dissolving right into solution has a positive entropy adjust (the solution becomes more chaotic). Therefore all of the listed reactions space a positive change in entropy, making E the exactly answer.

You are watching: Which of the following would represent an increase in entropy


Explanation:

Entropy can be assumed of together the propensity for a mechanism to come to be disordered, or random. Osmosis, melting ice, and a clean room ending up being dirty room all instances of entropy in ~ work. Each of these processes will occur spontaneously there is no the input of outside energy or work.

If you do a skyscraper, you are incorporating a collection of compounds and building commodities into a single, distinctive formation. Think of it this way: what space the odds that mommy nature would spontaneously develop a building? This process is an extremely ordered, which method that entropy of the universe has actually decreased.

Example question #10 : Entropy


Which reaction will result in a negative entropy?


Possible Answers:
Correct answer:


Explanation:

A reaction will have actually a positive change in entropy once the disorder of the device is increasing. This can happen when a liquid transitions to a gas, or more gas molecules are formed in the reaction.

Since 2 molecules of gas nitrogen dioxide can incorporate to kind one molecule the dinitrogen tetroxide, the amount of gaseous molecules is halved. This rises order, which decreases the entropy the the system.
