(D) High density

$\mathtt{\bf{\large{\underline {\green{More \: to \:know :-}}}}}$

✏ Materials like plastic are bad conductors or insulators of electricity as well as heat.

✏ They do not allows heat and electricity to pass through them.

✏ This is because electrons in it are are tightly packed, and charges cannot move freely. Hence, it doesn't contact heat and electricity.

✏ Examples :-

• Plastic is used in covering in electrical wires, which protects from electric shocks.

• Plastics are also used in the handles of frying pans, which stops heat to reach our hands.

• Plastics are used in switches to prevent electricity.

Answer 2

Answer:

Option [C] Bad conductors of heat.

Explanation:

Plastic is bad conductors of heat because they do not have any resistivity are at the bad conductors of electricity..
