Is polystyrene a conductor or a insulator or a semi conductor?
Polystyrene is considered an insulator because it is a poor conductor of electricity. It has high resistance to the flow of electric current due to the lack of free-flowing electrons in its structure.
Which cup keeps hot water the hottest polystyrene or metal?
Polystyrene (especially the expanded "Styrofoam (R)" type) is a good insulator. Metals are good conductors of heat.The insulating cup will maintain a greater heat differential than the conductor so if there is a liquid in the cup that is at a greater temperature than the surroundings, the metal cup will loose more heat than the polystyrene cup.
Is a polystyrene cup a good conductor of heat?
No, polystyrene is a poor conductor of heat because it has low thermal conductivity. This property makes it a good insulator, which is why it is commonly used for disposable cups to prevent heat transfer between the hot liquid and your hand.
Why would a polystyrene cup be a good insulator of heat?
Polystyrene is a substance that when in a solid state has a lot of holes. These holes trap air inside them and since air is a good insulator, the polystyrene cup is a good insulator. *Air is only a good insulator when not moving, hence why a breeze feels cold.
Is polystyrene a conductor?
polystyrene along with other porous (objects which have a lot of air in them) such as Styrofoam water, wood and other materials are insulators, not conductors.

Is Polystyrene a good thermal conductor?
No, polystyrene is a poor thermal conductor. Its structure with trapped air pockets makes it a good insulator, which means it does not conduct heat well. This makes polystyrene commonly used in thermal insulation applications.
Will a cup be an electrical conductor or an electrical insulator?
That depends on what the cup is made of. If it's a metal cup, then it's an electrical conductor. If it's a glass, clay, wood, or ceramic cup, then it's an electrical insulator.
Which is a better conductor wood or polystyrene?
Wood is a better conductor of heat than polystyrene. Polystyrene is a poor conductor of heat, making it a good insulator. Wood, on the other hand, conducts heat more efficiently due to its molecular structure.
Is expanded polystyrene a thermosetting or thermoforming plastic?
Polystyrene is a very poor conductor of heat. This is why its used as an insulator in some products.
How does a polystyrene cup keep drinks warm?
because it does
Is polystyrene a better insulator than metal?
Yes, polystyrene is a better insulator than metal. Polystyrene has a lower thermal conductivity, which means it is more effective at preventing the transfer of heat compared to metal. Metal is a good conductor of heat, so it allows heat to pass through easily.
Is a cup a conductors?
It's not the object that matters, but what it's made of . A metal cup will be a very good conductor, and an expanded polystyrene one a very poor conductor.
