Question

Which of these items is the best conductor of heat?

A. a metal fork
B. a wooden drawer handle
C. a solid plastic ladle
D. a foam plastic drink container

Answer 1

Answer: A. a metal fork

Explanation: Conduction (or the transfer of thermal energy) occurs when particles from warm matter interact with those of cooler matter and transfer some of their thermal energy to the cooler matter. Metals are such good conductors because they have more free electrons that can interact/transfer energy. Generally, metals and stone are good thermal conductors, while things like wood, paper, air, plastics, and cloth are not.
