The electronic conductance of a metal depends on its density.Does this mean that if we increase the density of the metal,its electronic conductance will increase?How does it happen?
You cannot change the density of a metal without also changing other properties.
Brass is a mixture of several elements. It can have different densities depending on the mixture of the elements. I haven't researched it, but the electronic conductance would likely be different for each type of brass.
Do you have a source for your statement?
The electronic conductance of a metal depends on its density.
