Unfortunately, I couldn't see the heating curve for Ethanol. However, I can provide you with the typical heating curve for Ethanol and the corresponding phases or phase changes:

A - Solid phase (Ethanol is in its solid state)
B - Melting/Fusion (Phase change from solid to liquid. The temperature remains constant during this phase change)
C - Liquid phase (Ethanol is in its liquid state)
D - Vaporization/Boiling (Phase change from liquid to gas. The temperature remains constant during this phase change)
E - Gas phase (Ethanol is in its gaseous state)
