[[Ice]] is an exception to this due to how the [[molecule]]s arrange themselves, see [[Ice-Water Anomaly]].: A [[substance]] which is [[solid]] at [[Room Temperature|room temperature]] has a larger [[force]] of [[attraction]] between [[particle]]s than a [[substance]] which is [[liquid]] or [[gas]] at [[Room Temperature|room temperature]]. {| class="wikitable"|+Solids|-| style="height:20px;
