Which statement best explains why metal cooking utensils often have plastic coating on their handles?

• A. Plastic reduces the transfer of thermal energy to hands holding the utensils.
• B. Plastic melts less easily and lasts longer than metal.
• C. Plastic molds more easily into shapes like long, thin handles.
• D. Plastic increases the rate of conduction from the utensil to the food.

Answer: (A)

The main idea here is heat transfer by conduction and how materials handle it. Metal conducts heat very well, so when a metal utensil sits in hot food or liquid, heat travels along the metal and toward the handle. A plastic coating has much lower thermal conductivity, acting as an insulating barrier that slows heat flow to your hand. This keeps the handle cooler and reduces the risk of burns, making the utensil safer and more comfortable to grip. The coating’s purpose isn’t about melting, shaping, or increasing heat transfer to the food; it’s about insulating the handle to protect the user.
