==Key Stage 2==
===Meaning===
[[Boiling]] is when a [[liquid]] is so hot that all of it is turning into a [[gas]].

===About Boiling===
: When a [[liquid]] '''boils''' bubbles form inside it. These bubbles are the same [[substance]] as a [[gas]].

===Note to Teachers===
The majority of students reaching secondary school do not know what the bubbles are made of when they observe water boiling. Answers to this question include; air, gas, hydrogen and oxygen. The more able students will generally state one of the latter two while few, if any, will state that it is water vapour or water gas. It appears that while students tacitly accept that boiling means liquid turning into gas, they don't fully understand the implications.

==Key Stage 3==
===Meaning===
[[Boiling]] is an [[endothermic]] process in which a [[subtsance]] turns from a [[liquid]] into a [[gas]] at its [[Boiling Point|boiling point]].

===About Evaporating===
: '''Boiling''' is a [[Reversible Changes|reversible]] process. When a [[liquid]] '''boils''' and becomes a [[gas]] you can [[condensing|condense]] that [[gas]] back into a [[liquid]].
: A [[liquid]] will [[boil]] when it has been [[heated]] to its [[Boiling Point|boiling point]].

| style="height:20px; width:600px; text-align:left;" |The [[particle]]s in the [[liquid]] move 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]].
|}

==Key Stage 4==
===Meaning===
[[Boiling]] is an [[endothermic]] [[Physical Change|physical change]] in which a [[substance]] turns from a [[liquid]] into a [[gas]] at its [[Boiling Point|boiling point]].

===About Boiling===
: [[Boiling]] happens when the [[particle]]s in a [[liquid]] have enough [[energy]] to break [[bond]]s holding them close to one another as they gain [[Potential Energy|potential energy]].
: The [[temperature]] at which a [[substance]] '''boils''' is called its [[Boiling Point|boiling point]].
: [[Boiling]] is an [[endothermic]] process, which means it needs to [[Absorb (Physics)|absorb]] [[energy]] to take place.
: [[Boiling]] is a [[Physical Change|physical change]], which means it is [[Reversible Changes|reversible]] and does not produce new [[chemical]]s.

{| class="wikitable"
|[[File:BoilingGraph.png|center|500px]]
|-
| style="height:20px; width:500px; text-align:left;" |As a [[liquid]] is [[heated]] the [[Internal Energy|internal energy]] increases. As the [[liquid]] '''boils''' the [[temperature]] of the [[substance]] stays the same but the [[Potential Energy|potential energy]] of the [[particle]]s continues to increase.
