==Key Stage 4==
===Meaning===
'''Intermolecular forces''' are [[force]]s that act between [[molecule]]s.
===About Intermolecular Forces===
: '''Intermolecular forces''' cause [[molecule]]s to be attracted to one another or different parts of a [[molecule]] may have a [[Negative Charge|negative]] or [[Positive Charge|positive charge]] which can cause them to arrange into specific shapes in a [[solid]].
: The strength of '''intermolecular forces''' determines the [[Melting Point|melting point]] and [[Boiling Point|boiling point]] of a [[substance]].
===Intermolecular Forces and State Changes===
: If a [[solid]] is [[heat]]ed enough the [[bonds]], holding the [[particle]]s in fixed positions, break allowing the [[particle]]s to move past each other, turning the [[solid]] into a [[liquid]].
: If a [[liquid]] is [[heat]]ed enough the [[particle]]s can move so fast that they escape the [[bonds]] holding the [[particle]]s to each other which allows them to leave the [[liquid]] to become part of a [[gas]].
: The stronger the '''intermolecular forces''' the higher the [[Melting Point|melting point]] and [[Boiling Point|boiling point]] of a [[substance]].
