Final answer:
Aluminum does not change color before it reaches its melting temperature.
Step-by-step explanation:
False
Aluminum does not change color before it reaches its melting temperature. Aluminum, in its solid form, typically has a silvery-white color. However, when it is heated to its melting temperature of 660.3 degrees Celsius, it undergoes a phase change and transitions into a liquid state. At this point, it does not change color but rather becomes a silver liquid.
Therefore, aluminum does not change color before it reaches its melting temperature.
