==Key Stage 4==
===Meaning===
'''Melting point''' is the [[temperature]] at which a [[solid]] can become a [[liquid]].
===About Melting Points===
: Different [[substance]]s have different '''melting points'''.
: The '''melting point''' of a [[substance]] is determined by the strength of the [[bond]]s which hold the [[particle]]s in fixed positions in a [[solid]]. The stronger the [[bond]]s the higher the '''melting point'''.
: When a [[substance]] is [[heated]] to its '''melting point''' it will remain at this constant [[temperature]] until all of the [[solid]] has [[melting|melted]].
: The '''melting point''' of [[pure]] [[water]] [[ice]] is 0[[°C]] or 273 [[Kelvin]].
: Adding [[salt]] to [[ice]] can lower its '''melting point''', causing it to [[melting|melt]] at a lower [[temperature]].
: [[Transition Metal]]s generally have very high '''melting points''', except for [[Mercury (Element)|Mercury]] which is [[liquid]] at [[Room Temperature|room temperature]].
