By electrolysis of melted aluminium a metal with a purity higher than 99,99 % can be obtained.
Aluminium oxide (Al₂O₃) is melted before electrolysis to lower its viscosity and enhance ionic mobility, allowing for more efficient conduction of electricity. The melting process also helps to break down the strong ionic bonds in the solid structure, facilitating the separation of aluminium ions from oxygen ions during electrolysis. This is crucial for producing pure aluminium in an energy-efficient manner. Additionally, molten aluminium oxide can be easily subjected to the electric current necessary for the electrolysis process.
The boiling point of aluminium is 2 470 0C.
Yes, melted metal can be solidified again by allowing it to cool and re-solidify. The process involves letting the melted metal cool down to its freezing point, at which point it will turn back into a solid state.

Blue litmus paper will turn red in the presence of aluminium hydroxide, indicating that the solution is acidic.
Because it melted....
Aluminium cans can be recycled indefinitely without losing quality. The recycling process allows the aluminium to be melted down and reformed into new cans, making it a sustainable material.
Aluminum is solidified at its melting (or freezing point which is the same): 660.32 °C (933.47 K, 1220.58 °F)
A wax candle can turn into a liquid when it is melted by heat. Once the melted wax cools down, it solidifies back into a solid state.
Firstly, the aluminium will turn to aqueous (like liquid) at its melting temperature (660 degrees Celsius). After this, it will turn to a gas at (2519 degrees Celsius); its boiling temperature. The transition from solid to liquid can be represented on a graph as a curve, y=lnx and the transition from liquid to gas is the curve y=e^x continuing from the former curve. A chemical reaction for this is; Al(s) + O2(g) => Al3+O2-(aq) ------ from solid to liquid (aqueous) Al2O3 => Al(s) + O2 ------ from liquid to gas Notice that the gas O2 is emitted, this is an importance aspect of chemistry since aluminium can be purify by this process. The aluminium is refined into its pure solid form.
well the wizard dies it melted
Selenium is melted at 221 oC.
Because you rock soo much that it melted the wireing!!
