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

A cup of ice at −15 degrees C



Which of the following systems has the lowest entropy?


Sugar crystals in a 95°C cup of coffee

Sugar crystals in a 27°C cup of coffee

Sugar crystals in a 53°C cup of coffee

Sugar crystals in a 15°C cup of coffee

Answer 1

entropy=enthalpy(heat)/temperature
entropy is a measure of chaos or disorder in a system
now think what the correct answer should be

Answer 2

okay for the first one..it would be A cup of ice at −15 degrees C

Answer 3

?

Answer 4

no
lets compare solids, liquids and gases ,now the physical structure of which one of these has the greatest disorder?

Answer 5

ok
A cup of water at 0 degrees C

Answer 6

yes

Answer 7

okay for the second one
it would be Sugar crystals in a 95°C cup of coffee?

Answer 8

yes

Answer 9

thank you for the help :)

Answer 10

ur welcome:)
