Answer
The cooling curve of that process is represented by the drawing:
- The segment represented by "a" corresponds to the solid physical state, that occurs between 0 and -10∘ C.
-------------
Work Step by Step
You can use the figure on the bottom of the page 81 as the basis to draw the cooling curve.
Since the melting/freezing point of water is at 0∘, at any value below that one, water will occur as a solid.
