On heating, the intermolecular force of attraction
Increases
Decreases
Remains the same
First increases, then decreases
On heating, the intermolecular force of attraction decreases as the molecules start moving away from each other.
What is the effect of latent heat on the force of attraction?
Breaks
Latent heat breaks the force of attraction between the molecules.
