: 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]].
===Examples===: Comparing In [[Group 7]] [[Fluorine]] is a [[gas]] at [[Room Temperature|room temperature]] while [[Iodine]] is a [[solid]] at [[Room Temperature|room temperature]] because the [[force]] of [[attraction]] between [[molecule]]s of [[Iodine]] is greater than the [[Halogenforce]] between [[molecule]]s of [[Fluorine]].: In [[Group 6]] [[Oxygen]] is a [[gas]] at [[Room Temperature|room temperature]] while [[IodineSulphur]] is a [[solid]] at [[Room Temperature|room temperature]] because the [[force]] of [[attraction]] between [[molecule]]s of [[Sulphur]] is greater than the [[force]] between [[molecule]]s of [[Oxygen]].
