$I$ . Salt water will evaporate more quickly than pure water.
$I I$ . Salt water has a higher level of entropy than pure water.

Question

Answer 1

Salt water will not evaporate more quickly than pure water.
This is because if salt is in water, the molecules of the salt will block the water from evaporating as evaporation is a surface phenomenon. Water is able to evaporate but not as fast.
The entropy of the salt solution is greater because when salt solution freezes its $S$ is more negative.
This is because salt water is more disordered due to $N a^{+}$ and $C l$ ions, and so it becomes more ordered when water freezes

Answer 2

Salt water will not evaporate more quickly than pure water.

This is because if salt is in water, the molecules of the salt will block the water from evaporating as evaporation is a surface phenomenon. Water is able to evaporate but not as fast.

The entropy of the salt solution is greater because when salt solution freezes its

S

is more negative.

This is because salt water is more disordered due to

N a^{+}

and

C l

ions, and so it becomes more ordered when water freezes
