Question

Which of the following systems has the highest entropy?

A cup of ice at 0 degrees C

A cup of water at 50 degrees C

A cup of water at 0 degrees C <----- my answer

A cup of ice at −15 degrees C

Answer 1

Entropy is also related to temperature higher temperature means more "randomness/ disordered state"

Answer 2

Also entropy increases as you go from solid<liquid<gas b/c particles are less ordered.

Answer 3

Am I wrong then?

Answer 4

I am confused now as to whether it would be B or C.

Answer 5

The difference between b and C is your temperature

Answer 6

If your temperature goes up you would expect a higher entropy

Why?
Because

TdeltaS would get bigger in your Gibbs free energy equation.

Also as temperature increases your average kinetic energy of particles does as well.

Answer 7

Knowing that what would be the answer?

Answer 8

so B?

Answer 9

@Photon336 B would be correct, not C?

Answer 10

B

Answer 11

A cup of water at 50 degrees has the least order and compactness as its molecules are in constant motion colliding each other with very high kinetic energy and hence due to its highest randomness among all, it has the largest entropy among others.

Answer 12

It is B, B has the least amount of order out of all the options and therefore has the highest entropy

Answer 13

Ok thank you all, I understand now, I misread one of the responses at first.
