Question

is the density of a metal (like aluminum) the same no matter what the size of aluminum?

Answer 1

yes. The density of a slab of aluminum the size of a railroad car is the same as the density of a piece of any other size; for example a piece that fits in your hand (if the aluminum is the same kind of aluminum--that is one piece can't be aluminum and the other piece an alloy of aluminum).

Answer 2

thank you!!
