The [[melting point]] of any substance is the [[temperature]] at which that substance changes state from a [[solid]] into a [[liquid]], or vice versa. Melting temperature for most substances is mildly related to the [[pressure]] on the system. If the pressure of a melting point is not specified, it probably describes a system at [[atmospheric pressure]].
