Melting point | Define Melting point at Dictionary.com

For a given substance, the melting point of its solid form is the same as the freezing point of its liquid form, and depends on such factors as the purity of the substance and the surrounding pressure. The melting point of ice at a pressure of one atmosphere is 0°C (32°F); that of iron is 1,535°C (2,795°F). See also state of matter.

Why Do Ionic Compounds Have High Melting and Boiling ...

Ionic compounds have high melting and boiling points because the ionic bonds that hold the compounds together are very strong and require a great deal of energy to break apart. A higher temperature indicates that more energy is being used. This extra energy is needed to break the electrostatic attraction that is present in an ionic bond.
