Answer:
A metal would typically have a higher thermal conductivity than a polymer/plastic.
Step-by-step explanation:
Metals generally have a higher thermal conductivity than polymers/plastics. This is because metals have a higher density of free electrons, which can easily transfer heat energy through the material. Polymers/plastics, on the other hand, have a lower density of free electrons and a more complex molecular structure, which makes it more difficult for heat to be conducted through the material. Additionally, polymers/plastics have a lower melting point than most metals, which means that they may begin to degrade or melt under high temperatures before heat can be effectively transferred through the material.
