Which of the following does not represent an increase in entropy?
Possible Answers:
Melting of mercury
NaCl dissolving in water
Boiling water
Sublimation of CO2
Condensation of water on glass
Correct answer:
Condensation of water on glass
Explanation:
Of phases, from greatest to least entropy is gas>liquid>solid. Dissolving a salt into solution is an increase in entropy because the salt has greater space to move. The only decrease in entropy is condensation of water on glass (gas to liquid)
