Answer
The heating curve of that process is represented by the drawing:
- The segment represented by "2" corresponds to the melting of the ice, that occurs between at 0$^{\circ}$ C.
Work Step by Step
You can use the Figure 3.8 (Page 81) as the basis to draw the heating curve.
Since the melting/freezing point of water is at $0^{\circ}$, the ice will absorb energy, and melt at that temperature.
