Explanation:

Copper has a greater ‘coefficient of thermal expansion’ than does iron. To my way of thinking, this would mean that the atoms in a piece of copper can vibrate more easily upon heating than can the atoms of a similar piece of iron. So, a vibrating copper atom will occupy proportionally more space upon heating to a certain temperature than a vibrating iron atom will. Thus, thermal expansion would be a function of the strength of ‘metallic' bonding in each metal. The stronger the inter-atomic bonding, the less atomic vibration there will be, so the degree of thermal expansion will be less. Iron is structurally stronger than copper for this reason. Iron's melting point is higher for the same reason. Tungsten, which has one of the lowest coefficients of thermal expansion, also has a very high melting point and very high tensile

Answer:

When two identical rods (same length) are of different material and heated to same rise in temperature ,the copper rod will expand more than iron , since expansion depends on nature of material .
