A piece of iron with the same dimensions as a piece of aluminium will be heavier because the atoms are more closely packed and each iron atom has much more mass than each aluminium atom.

Miss Roberts: OK, so we are looking at the conservation of mass. Now, mass is the measure of how much stuff or matter is in an object and it's measured in either grams or kilograms. Katie ...
