==Key Stage 3==
===Meaning===
'''Depositing''' is an [[exothermic]] process in which a [[gas]] turns directly into a [[solid]] without going through the [[liquid]] [[Stage State of Matter|state]].
: [[Noun]]: '''Deposition'''
| style="height:20px; width:600px; text-align:left;" |The [[particle]]s in the [[gas]] slow down until they are slow enough that [[force]]s between the [[particle]]s start to hold them together in fixed positions. The [[particle]]s become stuck in fixed positions and a regular arrangement which makes the [[State of Matter|state]] a [[solid]].

==Key Stage 4==
===Meaning===
[[Depositing]] is an [[exothermic]] [[Physical Change|physical change]] in which a [[gas]] turns into a [[solid]] without going through a [[liquid]] [[State of Matter|phase]].
===About Deposition===
: [[Depositing]] happens when the [[particle]]s in a [[gas]] form [[bond]]s that hold them together in fixed positions as they lose [[Potential Energy|potential energy]].
: '''Deposition''' is an [[endothermic]] process, which means it needs to [[Absorb (Physics)|absorb]] [[energy]] to take place.
: '''Deposition''' is a [[Physical Change|physical change]], which means it is [[Reversible Changes|reversible]] and does not produce new [[chemical]]s.
: [[Substance]]s may '''deposit''' depending on the [[pressure]] and [[temperature]] around them.
: Frost is the '''deposition''' of [[Water Vapour|water vapour]] in very low [[temperature]]s.
