In general, the molar heat of fusion for a substance is a smaller quantity than the molar heat of vaporization for the same substance.
The BEST explanation for this observation is which of the following?
Vaporization involves a greater change in molecular potential energy than does fusion.
Vaporization involves a greater change in molecular kinetic energy than does fusion.
Vaporization takes place at a higher temperature than fusion.
The intermolecular forces (IMF) in liquids are greater than the IMF in solids.
