Checked:
- a change from water vapor to liquid water (yes)
- a change from liquid water to solid water (yes)
- an increase in the temperature of water (yes)

Not checked:
- a change from liquid water to water vapor (no)
- a decrease in the temperature of water (no)

Brief reasoning: sound speed c ≈ sqrt(elasticity / density). Gases are much less stiff than liquids, so vapour → liquid raises c (liquid → vapour lowers c). Solids are stiffer than liquids, so liquid → solid raises c. Increasing the temperature of water (in the usual liquid range) increases the speed of sound; decreasing temperature lowers it.
