Here's a list of solids that change state when heated, along with their melting points:

Metals:

* Aluminum: 660.3 °C

* Gold: 1064.18 °C

* Iron: 1538 °C

* Lead: 327.46 °C

* Mercury: -38.83 °C (Mercury is actually a liquid at room temperature, but it solidifies at this temperature)

* Silver: 961.78 °C

* Tin: 231.93 °C

Non-metals:

* Sulfur: 115.21 °C

* Phosphorus (white): 44.1 °C

* Iodine: 113.7 °C

Other:

* Ice (water): 0 °C

* Salt (sodium chloride): 801 °C

* Sugar (sucrose): 186 °C

* Paraffin wax: 47-65 °C

* Butter: 32-35 °C

Important Note: This list is not exhaustive. Many other solids undergo a change of state when heated.

Key Concepts:

* Melting Point: The temperature at which a solid changes into a liquid.

* Boiling Point: The temperature at which a liquid changes into a gas.

* Phase Change: The process of changing from one state of matter (solid, liquid, gas) to another.
