The copper wire is cut into three pieces of unequal lengths. All three pieces of copper would have (1 point) A the same mass
B the seſme physical properties
C different crystal structures
D different arrangement of atoms

B.) The same physical properties.

Also the copper wire would also have the same Chemical Properties. They wouldn't have a different arrangements of atoms because that would mean they are a different substance. They wouldn't have the same mass whereas they are now in 2 pieces. Copper is not a crystal meaning it would not have any crystal structures. That leaves the only applicable answer to be B. Also in case you need to find whether or not two identical substances are the same would be by testing the melting point, hardness and solubility. I just finished working on this section in my own 8th grade Science class so I think this should either help you now or later on.

Hope this helps.
