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

1 answer:

4 0

Metal solids contain a positively-charged cation surrounded by a "sea" of delocalised, negatively-charged electrons.

The electrons are able to move freely, and hence transfer kinetic energy throughout the implement at a much quicker rate than non-metals.

Plastic is made of non-metals (Mostly carbon and hydrogen) and therefore is a poor thermal conductor.

Therefore, by coating the metal utensil in plastic, the rate of heat energy transfer to the person in contact's hand is decreased.
