Question

which of the following phase changes is the largest increase in entropy?○ evaporation○ deposition○ condensation○ sublimation○ freezing○ meltingquestion 23 ptswhich of the following phase changes is represented with the following equation? $h_2o_{(g)}
ightarrow h_2o_{(l)}$○ deposition○ freezing○ condensation○ melting○ evaporation○ sublimation

Explanation:

For Question 1: Entropy measures molecular disorder. Gases have far higher entropy than liquids or solids. Sublimation is the direct phase change from solid to gas, which creates the largest jump in molecular disorder compared to other options (evaporation is liquid to gas, melting is solid to liquid; deposition, condensation, freezing all decrease entropy).
For Question 2: The equation $\ce{H2O_{(g)} -> H2O_{(l)}}$ shows water changing from a gaseous state to a liquid state, which is the definition of condensation.

Answer:

1. sublimation
2. condensation
