Which material is most likely to inhibit heat flow in a household handle?

• A. Metal
• B. Glass
• C. Plastic
• D. Wood

Answer: (C)

What’s being tested is how well a material resists heat flow, which comes down to thermal conductivity. A handle should stay cool when you’re using the pot or pan, so you want a material that doesn’t transfer heat easily from the hot contents to your hand. Metal conducts heat very well, so it tends to get hot quickly in kitchen use. Glass also transfers heat more readily than a good insulator, though not as aggressively as metal. Wood is a fairly good insulator, but plastic is typically the best at keeping heat from passing through quickly among these options. Plastic has a relatively low thermal conductivity and often includes trapped air in its structure, both of which reduce heat transfer. It’s also practical for handles because it’s moldable, durable, and easy to clean. So, plastic is the best choice for inhibiting heat flow in a household handle.
