Describe in detail what you expect for the changes in enthalpy, entropy, and free energy when a sample of liquid evaporates. How does temperature affect these changes?
Which of the following processes has an increase in entropy?
a) boiling a pot of water
b) freezing a sample of water
c) filtering sand out of a sample of water
d) synthesizing water from hydrogen and oxygen
Which of the following changes has a decrease in entropy?
a)N2O4 (g) yields 2NO2 (g)
b) C6H6 (l) yields C6H6 (g)
c) 2LiClO3 (s) yields 3O2 (g) + 2LiCl (s)
d) 3Fe (s) + 2O2 (g) yields

Best ResponseYou've already chosen the best response.1Describe in detail what you expect for the changes in enthalpy, entropy, and free energy when a sample of liquid evaporates. How does temperature affect these changes? Evaporation is endothermic (DH>0) and is not affected by temperature In evaporation you go from an oredered structure to a gas which means DS >0 Since DG = DH  TDs this means that DG will be negative only if TDS > DH which means at higher temperatures.
