Plastic does poorly at insulating against heat; it absorbs it far too easily, and generally fails to deflect it, passing it to whatever it is insulating. However, plastic does not carry an electric current, and therefore is good insulation for wirse and electrical apparatus.
it depends on what type wooden: no metal: yes plastic: no
Plastic is generally a better insulator than metal because it has higher electrical resistance and lower thermal conductivity. This property makes plastic a good choice for applications where electrical insulation or heat retention is needed. Metal, on the other hand, is a better conductor of heat and electricity.
Aluminum is a better insulator than plastic because it has a lower thermal conductivity. This means that aluminum is better at preventing the transfer of heat than plastic. However, plastic can be better at blocking sound and electrical conductivity.
You can create a static charge on an insulator by friction, such as rubbing it with a cloth or fur. This causes electrons to transfer between the insulator and the material rubbing against it, leading to a buildup of static electricity on the insulator.
An insulator is a material that slows the flow of heat and electricity. It has high resistance to the flow of both heat and electrical current, which makes it useful for preventing heat loss or electrical shorts. Examples of insulating materials include rubber, wood, and plastic.
Plastic is typically considered to be a good electrical insulator because it does not conduct electricity well due to its high resistivity. However, there are certain types of plastic that have been engineered to be conductive for specific applications.

They're both related to the degree of freedom that their molecules' electrons have in moving about ; a metal's electrons are free to move to any adjacent atom, whereas a plastic usually has its electrons closely bound.
If door knob is a metal then it is conductor if not like wood then insulator.
Keys are usually made from some metal or alloy. If they are, they are good conductors, both of heat and of electricity.
well, i think both would be correct, though a "bad conductor of heat" would be better. Or you could say "insulator for heat" or simply insulator....
Yes, air is a good insulator.Yes, air is a good insulator of both heat and electricity

Aluminum will conduct both electric current and heat, so it would be a bad insulator of either.
Brass will conduct both electricity and heat. So brass is a conductor, but not an insulator.
