Question

If you are given two unknown samples of gray metals, how can you use physical properties to determine if they are the same

Answer 1

Answer: melting point, boiling point and density

Step-by-step explanation:

Every metal or element has it unique melting point and this is very helpful during analysis. The density is a function of its mass to volume ratio and no two different metals can have the same density except they're isomers. This is the easiest way to differentiate two metals with same colour.

Answer 2

You can apply the same physical assays to determine if both samples show the same results.

Step-by-step explanation:

You should check the same properties to both metals like Density, weight, melting point, boiling point after that you compare the resultes and they should be the same to ensure the samples are the same metal, if you see any different values the samples are not the same.
