Conduction

Question 3 • Fall 24 GSE Physical Science B IC

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

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

Explanation

Metal conducts thermal energy well, so heat from the cooking utensil can travel along its handle and burn your hand. Plastic is a poor conductor, so a plastic coating slows the transfer of heat to the person holding it. This makes “Plastic reduces the transfer of thermal energy to hands holding the utensils” the best explanation.
