Final answer:
The melting point of aluminum metal is not an intensive property.
Step-by-step explanation:
An intensive property is a property of a substance that does not depend on the amount of the substance. Instead, it is intrinsic to the substance itself. The density of a substance is an intensive property because it remains the same regardless of the size of the sample. In the given options, the melting point of aluminum metal is not an intensive property because it can vary depending on external conditions such as pressure.
