Melting and freezing take place at the melting point, boiling and condensing take place at the boiling point. - The amount of energy needed to change state from solid to liquid and from liquid to gas depends on the strength of the forces between the particles of the substance. The stronger the forces between the particles the higher the melting point and boiling point of the substance.
