Not exactly sure what you're asking but I'll give it a shot. Intermolecular forces do not change when a substance undergoes a phase change, such as when something goes from a solid to a liquid. The same intermolecular forces that existed when something was a solid still exist when it changes to a liquid, and vice versa. Its just that with the addition of an external factor (most commonly an increase in temperature) a substance is able to overcome the attractive forces in the solid and break apart into a liquid or when a liquid turns into a gas. For when something freezes or condenses the opposite happens, an external factor (most commonly a decrease in temperature) causes a given substance to be attracted to itself more strongly and then the substances comes together as either a liquid or a solid.
In summary: The forces do not change. Just how much the forces effect the overall substance changes.
The intermolecular forces within a solid are stronger than the similar forces in a liquid or a gas; as a consequence solids are harder, denser, having generally high melting and boiling points.
These are polar forces, intermolecular forces of attraction between molecules.
Dipole forces and London forces are present as intermolecular forces in these molecules.
These are intermolecular forces.
The intermolecular forces in acetone are weaker.
hydrogen bonding
In solid, the molecules r tightly packed by intermolecular forces, but in gas these forces r very loose.
These are polar forces, intermolecular forces of attraction between molecules.

Intramolecular forces are not intermolecular forces !

The intermolecular forces in acetone are weaker.

The weakest of the four forces is gravity by a huge margin
The intermolecular forces are hydrogen bonding.
When there is more thermal energy, then there are less intermolecular forces.
no solids are not in same shape they differ according to their shape and size due to intermolecular forces of attraction. submitted by sapan
