There is a large temperature interval between the melting point and the boiling point of a metal because?
metals have very high melting points
metals conduct heat very repaidly
melting does not break the metalic bond but boiling does
the crystal lattice of metals is easily broken
Penjelasan
The significant difference between a metal's melting and boiling points stems from the strength of the metallic bonds and the energy required to break those bonds during phase transitions. Melting involves loosening the attractive forces, while boiling requires complete breakage of those forces, demanding more energy.
