===About Subliming===
: Only a few [[solid]]s '''sublime'''. [[Freezing|Frozen]] [[Carbon Dioxide]] will [['''sublime]] ''' which means it skips the [[liquid]] [[State of Matter|state]].
: '''Sublimation''' is a [[Reversible Changes|reversible]] process. When a [[solid]] '''sublimes''' into a [[gas]] you can [[depositing|deposit]] that [[gas]] back into a [[solid]].
: Heating a [[solid]] will cause it to '''sublime''' into a [[gas]].
| style="height:20px; width:600px; text-align:left;" |The [[particle]]s in the [[solid]] [[vibrate]] faster until they are moving fast enough that they break the [[bond]]s holding the [[particle]]s together. The [[particle]]s become free to move anywhere which makes the [[State of Matter|state]] a [[gas]].

===Meaning===
[[Subliming]] is an [[endothermic]] [[Physical Change|physical change]] in which a [[solid]] turns into a [[gas]] without going through a [[liquid]] [[State of Matter|phase]].
 
===About Subliming===
: [[Subliming]] happens when the [[particle]]s in a [[solid]] break [[bond]]s holding them together in fixed positions as they gain [[Potential Energy|potential energy]].
: [[Subliming]] is an [[endothermic]] process, which means it needs to [[Absorb (Physics)|absorb]] [[energy]] to take place.
: [[Subliming]] is a [[Physical Change|physical change]], which means it is [[Reversible Changes|reversible]] and does not produce new [[chemical]]s.
: [[Substance]]s may '''sublime''' depending on the [[pressure]] around them. In [[Atmospheric Pressure|atmospheric pressure]] (101,000Pa) [[Carbon Dioxide]] and [[Iodine]] will both '''sublime''' and cannot exist in a [[liquid]] [[State of Matter|state]]. However, under extremely high [[pressure]] [[Carbon Dioxide]] can be turned into a [[liquid]].
: [[Ice]] will '''sublime''' in a [[vacuum]] but not in normal [[Atmospheric Pressure|atmospheric pressure]].
