Answer:
Silver, copper, metals
Step-by-step explanation:
In general, metals excel at conducting heat due to the free movement of electrons within their structures. Among metals, silver and copper are particularly efficient conductors with high thermal conductivity. In contrast, non-metallic substances like wood, plastic, and rubber tend to be poor conductors as heat is transferred through the less effective mechanism of atomic or molecular vibrations. Variations in thermal conductivity exist within both metal and non-metal categories, influenced by factors such as density and composition. Overall, metals, especially those with high thermal conductivity like silver and copper, stand out as the most effective heat conductors.
