Question

Which of the following systems shows an increase in entropy?

building a house of cards
water freezing into ice
spilling a jar of pennies
steam condensing to liquid water

Answer 1

I think spilling a jar of pennies would surely show an increase in entropy, since the pennies that drop on the floor would be at random. This is the best choice I can pick up with my definition of entropy.
