At what temperature does aluminum melt?

Aluminum has a melting point of approximately 1220 degrees Fahrenheit, making choice B the correct answer. This specific temperature is important for various applications, such as metallurgy and fire investigations, because the melting point indicates when aluminum transitions from solid to liquid. Understanding this property of aluminum can assist fire investigators in determining whether aluminum components in a fire scene were subjected to temperatures high enough to cause melting, which can provide insights into the severity of the fire and the potential origins of the incident.

The other temperatures provided are not accurate for aluminum's melting point; knowing the correct melting temperature is crucial for accurate interpretations in fire investigation scenarios.
