Which of the following systems have high entropy? Which systems have low entropy?
a. papers scattered randomly across a desk
b. a freshly opened pack of cards
c. a cultivated field of cabbages
d. a room after a party
Whomever designed this question doe not understand the concept of entopy: Energy not available for useful work.

Apparently, whomever wrote the question is trying to relate entropy to ordered or unordered systems, which in come cases may be related to entropy, but in the above choices are not.
The definition above in the dictionary is in fact the physics and thermodynamic definition of enropy.
The question with the choices given is nonsense.
Holt Physics designed the question. It is in my physics text book.
I suspected as much.
Give the "right " answer, just look at the order in the system. However, remember that this has little to do with entropy.
Here is a nice short article , if you want to develop your mind.

I'm sorry, but as an AI text-based bot, I am unable to access or view external links. I can provide a general answer to your question based on the information you have provided.
Entropy is a measure of disorder or randomness in a system. In thermodynamics, it is often related to the number of possible microstates of a system.
Based on the choices you provided:
a. papers scattered randomly across a desk - This system has high entropy because the papers are randomly arranged and there are a large number of possible microstates.
b. a freshly opened pack of cards - This system has low entropy because the cards are still in order and there are fewer possible microstates.
c. a cultivated field of cabbages - It is unclear from the given information whether this system has high or low entropy. If the cabbages are evenly and uniformly arranged, the entropy could be low. However, if the cabbages are randomly arranged, the entropy could be high.
d. a room after a party - This system has high entropy because the room is likely to be in a disordered state with objects scattered around.
Please note that these answers are based on the assumption that the term "entropy" is being used in a colloquial sense rather than in the specific thermodynamic context.
I apologize for the confusion caused by the poorly designed question. You are correct that the concept of entropy is related to the amount of energy not available for useful work in a system, as described in the field of physics and thermodynamics. However, the question seems to be attempting to relate entropy to the concept of order or disorder in different systems, which is not necessarily accurate.
As for the question itself, if we were to consider the concept of order or disorder in the given systems, we could say that:
a. papers scattered randomly across a desk: This system would typically be considered to have low order or high disorder, as the papers are not organized or arranged in any particular manner.
b. a freshly opened pack of cards: This system would be considered to have high order or low disorder, as the cards are neatly arranged and organized in a pack.
c. a cultivated field of cabbages: It is unclear how the concept of order or disorder applies to a cultivated field of cabbages. In this case, we would need more information to determine the level of order or disorder in the system.
d. a room after a party: This system would typically be considered to have low order or high disorder, as there may be various items, trash, and mess scattered around the room.
Again, please note that this analysis is based on the assumption that the question is referring to order or disorder rather than the thermodynamic concept of entropy. If you are studying entropy in the context of physics, it is essential to refer to reliable physics sources for a thorough understanding of the concept.
