Worked Solution

Step 1: The base needs to transfer heat from the stove to the food quickly (good conductor). Step [2-9]: The handle needs to stay cool so it can be held safely (poor conductor). Step [2-9]: Steel is a good conductor; wood and plastic are poor conductors.

Correct answer: Steel conducts heat quickly to the food; wood prevents heat from reaching the hand.
