Sarah needs to replace part of the metal railing on her deck and wants the new railing to match the existing railing. However, she does not know what metal the railing is made from. Which is a property that she can use to identify the metal?
#1electrical conductivity
#2surface area of the railing
#3solubility
There are many ways to test and identify metal. The easiest way is to observe the color of the metal. Also how reflective it is. Other ways would be boiling point, melting point, density or conductivity of the metal.
