Which of the following properties of a liquid increase as the strength of intermolecular forces increases?
I. enthalpy of vaporization
II. boiling point
III. surface tension

Question

Quizplus · Accepted Answer

As the strength of intermolecular forces in a liquid increases, the enthalpy of vaporization (energy required to convert a liquid into a gas at its boiling point), boiling point (temperature at which a liquid's vapor pressure equals the external pressure), and surface tension (the elastic tendency of a fluid surface which makes it acquire the least surface area possible) all increase. This is because stronger intermolecular forces require more energy to overcome, leading to higher values for these properties.
