Answer
The cooling curve of that process is represented by the drawing:
- The segment represented by "e" corresponds to the gas physical state, that occurs between 110 and 100 $^{\circ}$ 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 boiling point of water is at 100$^oC$, at any temperature above this one, water will occur as a gas (steam).
