which one of the following processes produces a decrease of the entropy of the system? a. sublimation of naphthalene b. dissolving sodium chloride in water c. dissolving oxygen in water d. explosion of nitroglycerine e. boiling of alcohol

Homework Answers

Answer #1

a. sublimation of naphthalene

This is change from solid to gas

This will increase entropy

b. dissolving sodium chloride in water

This is change from solid to aqueous

This will increase entropy

c. dissolving oxygen in water

This is change from gas to aqueous

This will decrease entropy

d. explosion of nitroglycerine

This is change from solid to gas

This will increase entropy

e. boiling of alcohol

This is change from liquid to gas

This will increase entropy
