- The uses of Aluminium include being used for industrial applications, cookware, transportation, and many more.
- They resist corrosion and can be easily recycled.
- It has a higher melting point than most metals.
- The melting point of Aluminium is 660 °C.
- The boiling point of Aluminium corresponds to 2519 °C.
- The object's shape doesn't determine the melting of metals; rather, different-shaped things would melt at the same temperature.
Hence, the correct answer would be option D) All the objects-the spoon, fork, and knife will melt at the same temperature of 660 °C.
