Melting and freezing of materials is dependent on their temperature. When something melts the liquid is the same substance as the solid. Not all solids melt on heating (they may burn or decompose).
When something dissolves an additional substance (the solvent) is needed. Dissolving can involve chemical changes (for example, antacid tablets mixing with water or metal dissolving in acid).
