Worked Solution

Step 1: The base needs to transfer heat from the stove to the food (needs a good conductor). Step 2: The handle needs to stay cool for the user to hold (needs a poor conductor). Step 3: Metal is a good conductor; plastic is a poor conductor.

Correct answer: Metal allows heat to pass through to the food quickly.
