Which Has More Entropy: a Shuffled Deck of Playing Cards

question 34

Multiple Choice

Which has more entropy: a shuffled deck of playing cards or an unshuffled deck of the same make and brand?

• A)These cards have the same entropy because they are made of the same material, have the same mass, and are at the same temperature.
• B)The shuffled deck has more entropy since it has a greater measure of disorder.
• C)The unshuffled deck has more entropy because it comes packaged with a totally random order of appearance. Shuffling the deck ultimately adds order and reduces entropy.
• D)The difference in entropy in the two decks could only be determined after examining both stacks of cards side by side once the unshuffled deck had been shuffled.
