What conclusion can be drawn about the heat of vaporization of ethanol from the heating curve? a) the potential energy of the ethanol molecules increases through vaporization. b) the temperature increase converts bonding forces into intermolecular forces. c) the kinetic energy of vaporization represents a greater change of stored energy. d) the ethanol is stabilized by strong intermolecular forces between the molecules.

Answer  The ethanol is stabilized by strong intermolecular forces between the molecules.wer:

Explanation:

During the phase change represented by the heat of fusion the temperature does not change. The molecules in the liquid state has a higher degree of freedom but are stabilized by the strong hydrogen bonding requiring a larger into of energy to separate the molecules than the heat of fusion.
