Worked Solution

Step 1: The body of the pan needs to transfer heat from the stove to the food quickly, so it must be a good conductor (metal). Step 2: The handle must prevent heat from reaching the hand, so it must be a poor conductor (plastic/wood).

Correct answer: Metal is a good conductor of heat while plastic is a poor conductor.
