Is Polystyrene a good thermal conductor?
No, it's not, though it's better than you might think if you equate polystyrene with Styrofoam. Styrofoam is made of polystyrene, but it's the trapped air that makes it such a good insulator.
Are silver paper clips a conductor or an insulator?
Silver makes it a conductor.
What makes aluminum conductor heat?
it has energy
Is tin foil a good insulator?
What we usually refer to as tin foil is almost always aluminum foil. Aluminum is a very good conductor of heat, and aluminum foil makes a very poor insulator. The exception might be in the case of radiant energy, which it reflects well, and even better when it is polished.
How can you tell wether a aluminum pan conducts heat?
You can feel the heat coming off of the pan!!!! Roller Coasters
Why are cool boxes lined with expanded polystyrene with air bubbles in it?
Air is a poor conductor of heat. Likewise, the thin walls of the bubbles of polystyrene are poor conductors. Bubbles of air, rigidly fixed in a polystyrene matrix, cannot transfer heat by convection. That leaves reducing radiation as the only unaddressed mechanism for controlling heat loss. Its low cost and ability to be molded makes expanded polystyrene an economical choice for an effective insulator.
Does electricity flow through conductors?
Yeah... That's what makes it a Conductor and not an Insulator.
Is lycra a good insulator?
Lycra is not good conductor of electricity. This is what makes it a good insulator together with most of the other fabrics.
Is wool conductor of heat?
Wool holds lot of air. As air is a bad conductor of heat, this makes the wool a bad conductor of heat, but a good insulator.
Is a pan a insulator or conductor?
An aluminum pan is a conductor, which makes it useful for cooking, since it heats up when placed on a burner or over a flame.
Is a pipe cleaner a insulator and a conductor?
it makes a good conductor because it is steel, but not so great as an insulator. this is simply because there is space between the fibers on the outside, and that something could come in contact with the steel wire.
What terms describe the metallic core of a wire?
conductorThe core of a wire is the center, the metal part. And insulator is the wrapping on the outside, and it makes sure that the electricity doesn't harm you. Electricity must have a conductor to work, and metal is an excellent conductor.
