Question

which of these is a good example of an insulator? a rubber pot holder a piece of aluminum foil a stainless steel pan

Explanation:

An insulator is a material that does not conduct heat or electricity well. Rubber is a poor conductor of heat, which is why it is used as a pot holder to protect hands from the heat of the pot. Aluminum foil and stainless steel are good conductors of heat (and electricity), so they are not insulators.
