Final answer:
Copper and Iron from the list provided are good conductors of heat due to their high density of free electrons. Wood and Foam are poor conductors and act as insulators.
Step-by-step explanation:
The substances from the list that are good conductors of heat are Copper and Iron. These materials are classified as good thermal conductors because they have a high density of free electrons that facilitate the transfer of thermal energy.
Good thermal conductors such as Copper, which is also used in cooking utensils for its thermal properties, are often also good electrical conductors. On the other hand, materials like Wood and Foam are poor conductors of heat and are considered insulators, often having small pockets of air within them that contribute to their poor thermal conductivity.
