What physical properties, other than specific heat could you use to help you identify the sample(s) used in this experiment?

What experiment? What kind of sample? Specific heat tells me you must have been heating/cooling something. How about density. That will identify many metals and is a physcal property.

OP Here

Edit: The experiment was to heat a certain metal in boiling water and take the temperature. Next we moved it into a makeshift calorimeter and found the specific heat of the metal. I ended up looking up the specific heat of the metal and I'm confident the metal we experimented with is aluminum.
Of course this is not what the question was asking. What properties could we have measured realistically in the experiment that would have let us know that?

I don't think so. I think the question is asking what physical property could you have measured that would help you determine the identity of the metal. Density? You would have had to look that up, too, in tables. There is no way you can get the Al metal to shout at you, "Hey, I'm aluminum". You must measure some property, then look up in a set of tables to find it.

To identify a sample in an experiment, other than specific heat, you can consider various physical properties. Some of the physical properties that can be helpful for identification are:

1. Density: The density of a substance can provide valuable information as different substances have different densities. You can determine the density by dividing the mass of the sample by its volume. Compare the calculated density with the known densities of various substances to identify the sample.

2. Melting and boiling points: Every substance has a unique melting and boiling point. By comparing the observed melting or boiling point of the sample with known values, you can narrow down the possibilities of what the sample might be.

3. Solubility: Different substances have varying solubilities in different solvents. By testing the solubility of the sample in different solvents, you can eliminate certain substances based on their solubility characteristics.

4. Conductivity: Electrical conductivity can also help in the identification process. Some substances are conductive, while others are insulators. By measuring the electrical conductivity of the sample, you can classify it as a conductor or insulator, which can aid in identification.

5. Color and appearance: Visual observation of the sample's color and overall appearance can provide clues for identification. Although color may not be a definitive criterion, it can serve as an initial indicator.

Remember that a combination of these properties is typically necessary for accurate identification. Using a combination of methods will increase the reliability of identification. It is important to consult reference materials and databases that provide information about the properties of different substances to make a conclusive identification.
