Metal is a very poor thermal (and electrical) insulator. It is a good conductor of heat (and electricity, obviously). Copper (a metal) is one of the best thermal conductors known to man--most laptops use pieces of copper to transfer the heat from the processor and graphics chips to the heatsync (typically aluminum), where the fan can remove the heat.
Materials like foam, rubber, etc. are good thermal insulators (think of pot holders...).

Which of the following is the best thermal insulator APEX?
Air (Explanation): water has a high specific heat capacity, but it can boil. stone (😂) also is a good thermal insulator, but it can get really hot. Metal is a very good thermal conductor, so it is definitely not that. Therefore, air is the best (its also really hard to boil).

Is plasticine a conductor or insulator?
Plastic is an electrical and thermal insulator.
Is a silver bracelet a conductor or insulator?
Silver is the best conductor there is, no matter what it is made into.
What are thermal insulators?
A thermal insulator slows or stops the passage of heat through it.
Is the best thermal insulator A. Stone Water C. Air Metal?
Air is the best thermal insulator among the options provided. Air has low thermal conductivity, meaning it is effective at trapping heat and preventing its transfer. Stone, water, and metal have higher thermal conductivities compared to air.
What is a very good thermal insulator?
oxygen.is the best insulator

Which material is a poor thermal insulator?
Metal is a poor thermal insulator because it allows heat to easily pass through it due to its high thermal conductivity. This means that metal objects can quickly reach the same temperature as their surroundings, making them ineffective at maintaining thermal insulation.
Is a radiator a thermal insulator or thermal conductor?
A radiator is a thermal conductor. It is designed to absorb heat and transfer it away from the source to be dissipated into the surrounding environment.
Is a plastic spatula a thermal conductor or a thermal insulator?
A plastic spatula is a thermal insulator, meaning it does not easily conduct heat. This is because plastic is a poor conductor of heat compared to materials like metal.
Is a glass a thermal insulator?
insulator. it is not a very good insulator though.
Which is an example of a good insulator?
it depends what type of insulator youre talking about. wood is a good thermal insulator and rubber is a good electrical insulator A perfect vacuum is the best insulator.
Is stone the best thermal insulator?
No, stone is not the best thermal insulator. Materials like fiberglass, foam, and cellulose are much better insulators due to their low thermal conductivity and ability to trap air pockets that reduce heat transfer. Stone is a poor insulator because it has high thermal conductivity, meaning heat can easily pass through it.

Metal plastic glass or ceramic What is the best insulator?
Ceramic is the best insulator among these materials due to its ability to withstand high temperatures and resist conductive heat transfer. It is also non-reactive and has low thermal conductivity, making it ideal for insulating applications.
Why is sliver not the best insulator?
Sliver, also known as metal foil, is not the best insulator because metals are good conductors of heat and electricity. They have a high thermal conductivity, which means they allow heat to transfer easily. This property makes them poor insulators compared to materials such as plastic or glass.
