Answer
The copper rod heated by 10°C will expand more than the rod heated by 5°C because if two identical rods of same metal and same length are heated to different temperatures, the rod heated to higher temperature expands more than the rod heated to lower temperature. More the increase in temperature of the rod greater will be the increase in its length.
