How is the enthalpy of vaporization related to intermolecular forces during a phase change? a) the temperature increase converts bonding forces into intermolecular forces during vaporization. eliminate b) the intermolecular energy of vaporization represents a greater change increasing the bonding forces. c) the kinetic energy of the ethanol molecules increases strength of the intermolecular forces increases. d) the liquid state is stabilized by the molecule's intermolecular forces resulting in a high enthalpy of vaporization.
