Question

thermal insulators

• rubber
• wood
• plastic
• fiberglass
• foam

thermal conductors

• metal
• ceramic
• concrete
• graphite
• diamond

you are building an electronic device that needs to transfer heat energy across distance. what would be a good material to use for this?
none of these would be good
wood
diamond
rubber

Explanation:

To transfer heat energy, we need a thermal conductor (materials that allow heat to flow easily). Thermal insulators (like Wood, Rubber) resist heat transfer. From the options, Diamond is a thermal conductor (listed under Thermal Conductors), while Wood and Rubber are insulators. So Diamond is a good choice for heat transfer.

Answer:

Diamond
