7. Name a physical property that is:

Question

(a) shared by gold, copper, and iron
(b) shared by gold and copper but not iron
(c) shared by diamond and glass
(d) not shared by diamond and glass

Answer 1

Sure! Here are the physical properties based on your categories:

(a) Shared by gold, copper, and iron: High density. All three metals have relatively high densities compared to many other materials.

(b) Shared by gold and copper but not iron: Malleability. Both gold and copper are highly malleable, meaning they can be hammered or pressed into thin sheets, while iron is less malleable.

(c) Shared by diamond and glass: Transparency. Both diamond and glass are transparent materials, allowing light to pass through them.

(d) Not shared by diamond and glass: Hardness. Diamond is one of the hardest known natural materials, while glass is significantly softer and can be scratched easily compared to diamond.
