Explanation:
mixture contain different types of substances in different compositions.
these substance may have different melting andboiling point hence the melting and boiling point of a mixture cannot be fixed.
proof: If you heat salt water, the boiling point will exceed 100 Celcius. However there are also impurities can lowers the melting and boiling point during heating. Example, cryolite (Na3AlF6) are added to aluminium oxide when heating to turn it to molten form.
