Select the most accurate statement about the heating curve shown for ethanol $$\left({\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\right)$$. The portion of the heating curve labeled " $$A$$ " represents the increase in the average potential energy of the liquid phase of ethanol. The portion of the heating curve labeled " $$B$$ " represents the phase change from liquid to gas phase, which is an increase in the average potential energy of the ethanol. The portion of the heating curve labeled " $$C$$ " represents an increase in the average kinetic energy of the liquid phase of ethanol. The portion of the heating curve labeled " $$C$$ " represents the increase in the average kinetic energy of the liquid phase of ethanol along with a phase change to the vapor. The portion of the heating curve labeled " $$A$$ " represents the vaporization of ethanol.
