How can iodine have a melting point?

Answer 1

All substances have melting points and boiling points. A melting point is merely the temperarture at which it changes from a solid to liquid and vice versa. The boiling point of a substance would be the temperature at which it changes from liquid to gas and vice versa.

Answer 2

Iodine has a melting point because it is a solid at room temperature and can transition to a liquid state when heated above its melting point of 113.7 degrees Celsius. This physical change occurs due to the breaking of intermolecular forces that hold the iodine atoms together in a solid lattice structure.
