==Key Stage 2==
===Meaning===
'''Condensing''' is when a [[gas]] turns into a [[liquid]].
: [[Noun]]: '''Condensation'''
: [[Verb]]: '''To condense'''
: [[Present Participle]]: '''Condensing'''
{| class="wikitable"
|+ When you cool a [[gas]]:
| style="height:20px; width:600px; text-align:left;" |A [[gas]] will '''condense''' to become a [[liquid]].
|}
===About Condensing===
: Cooling a [[gas]] will cause it to '''condense''' into a [[liquid]].
: '''Condensing''' is a [[Reversible Changes|reversible]] process. When a [[gas]] '''condenses''' into a [[liquid]] you can [[Evaporating|evaporate]] that [[liquid]] back into a [[gas]].
: You may have seen water '''condensing'''.

===Meaning===
'''Condensing''' is an [[exothermic]] process in which a [[gas]] turns into a [[liquid]].

The [[particle]]s end up touching but can still move past each other which makes the [[State of Matter|state]] a [[liquid]].

==Key Stage 4==
===Meaning===
[[Condensing]] is an [[exothermic]] [[Physical Change|physical change]] in which a [[gas]] turns into a [[liquid]].
===About Condensing===
: [[Condensing]] happens when the [[particle]]s in a [[gas]] form [[bond]]s holding them together as they lose [[Potential Energy|potential energy]].
: The [[temperature]] at which a [[substance]] '''condenses''' is the same as the [[temperature]] at which it [[boiling|boils]] so it is the [[Boiling Point|boiling point]].
: [[Condensing]] is an [[exothermic]] process, which means it [[emit]]s [[energy]] when it takes place.
: [[Condensing]] is a [[Physical Change|physical change]], which means it is [[Reversible Changes|reversible]] and does not produce new [[chemical]]s.

| style="height:20px; width:500px; text-align:left;" |As [[energy]] is removed from the [[gas]] it '''condenses''' and the [[temperature]] of the [[substance]] stays the same.
