==Key Stage 4==
===Meaning===
'''Boiling point''' is the [[temperature]] at which all of the [[particle]]s in a [[liquid]] gain enough [[energy]] to form a [[gas]].
===About Boiling Points===
: Different [[substance]]s have different '''boiling points'''.
: The '''boiling point''' of a [[substance]] is determined by the strength of the [[bond]]s which hold the [[particle]]s close together in a [[liquid]]. The stronger the [[bond]]s the higher the '''boiling point'''.
: When a [[substance]] is [[heated]] to its '''boiling point''' it will remain at this constant [[temperature]] until all of the [[liquid]] has [[boiling|boiled]].
: The '''boiling point''' of [[pure]] [[water]] is 100[[°C]] or 373 [[Kelvin]].
: Adding [[salt]] to [[water]] can increase its '''boiling point''', causing it to [[boiling|boil]] at a higher [[temperature]]. This is because the [[salt]] increases the [[force]] of [[attraction]] between [[adjacent]] [[particle]]s.
: The [[Nobel Gases]] all have very low [[Boiling Point|boiling points]] because there is a very weak [[force]] between the [[atom]]s.
