Answer:

Explanation:
Hello,
In this case, we can analyze the colligative property of solutions - freezing point depression - for the formed solution when ethylene glycol mixes with water. Thus, since water freezes at 0 °C, we can compute the freezing point of the solution as shown below:

Whereas the van't Hoff factor for this solute is 1 as it is nonionizing and the molality is:

Thus, we obtain:

Best regards.
A phase change from Gas to liquid means that it was cold outside and so the molecules went from being very free moving to forming bonds with one another due to the cold.
if I'm not mistaking it would be the second option
