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

Answers

Answer 1

Answer: 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.

Answer 2

Answer:

Answer:

Plastic reduces the transfer of thermal energy to hands holding the utensils.

What kind of ions do metals form

Answers

Answer: cations

Explanation:

Metals are defined as the elements which loose electrons to attain stable electronic configuration. If an atom looses electrons, it leads to the formation of positive ions known as cations.

For Example: Sodium looses 1 electron to form $Na^+$ ions.

Non-metals are defined as the elements which gain electrons to attain stable electronic configuration. If an atom gains electrons, it leads to the formation of negative ions known as anions.

For Example: Fluorine gains 1 electron to form $F^-$ ions.

Answer:

cations

Explanation:

metals are made of postively charged ions
