C The kinetic energy of the ethanol molecules increases strength of the intermolecular forces increases.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.

Answer 1

The correct response is:

D The liquid state is stabilized by the molecule's intermolecular forces resulting in a high enthalpy of vaporization.

Explanation: Enthalpy of vaporization reflects the amount of energy required to overcome the intermolecular forces that hold the liquid molecules together when transitioning to the gaseous state. Stronger intermolecular forces result in a higher enthalpy of vaporization, as more energy is needed to break these forces and allow the molecules to escape into the vapor phase.
