Insulators are often porous because they contain small air pockets or gaps between molecules. This allows them to trap heat or slow down the transfer of electricity by hindering the movement of electrons through the material. The presence of these air pockets gives insulators their characteristic thermal and electrical insulating properties.

Is polystyrene a conductor?
No, polystyrene is an insulator, not a conductor. It does not readily allow the flow of electricity through it.
Is a paper towel an insulator?
Yes, paper towels can act as insulators because they are made of porous materials that trap air, which is a good insulator. They can help prevent heat transfer and retain warmth when used in certain applications.
What is the part of speech for insulators?
The word "insulators" functions as a noun. It refers to materials or substances that do not conduct electricity or heat effectively.
What are some insulators and conductors?
Insulators: rubber, plastic, glass. Conductors: copper, aluminum, gold.
What is the name for materials that do not allow heat to pass?
Materials that do not allow heat to pass are insulators. (In real life, there are no perfect insulators, but if not much heat passes, then it is an insulator.)
Are tissues good insulators?
Tissues are not good insulators in terms of their ability to block heat transfer. They are thin and porous, allowing heat to easily pass through them. Materials like wool, styrofoam, or fiberglass are more effective insulators because they have low thermal conductivity and trap air pockets to inhibit heat transfer.
Is polystyrene a conductor?
No, polystyrene is an insulator, not a conductor. It does not readily allow the flow of electricity through it.
How are porous materials used as thermal insulators?
actually the insulator is the dead air in the pores a better insulator is vacuum (only radiation) air has conduction convection and radiation air is easier to handle near sea level
Is a concrete non porous?
There are two types porous and non porous. You can also seel porous concrete to make it non porous.
Is concrete non porous?
There are two types porous and non porous. You can also seel porous concrete to make it non porous.
Are Crayons insulators or conductors?
insulators
Is silk porous or nonporous?
Silk is porous -- it absorbs liquids.
Is metal porous?
Metal is not porous. Many other elements are porous though and when metal combines with them it can potentially become porous.
Does metamorphism make the rock more porous or less porous?
more porous
What a good sentence for porous?
The story proved to be quite porous. Lava is a porous rock.
What do you call poor conductors?
Poor conductors of electricity are often referred to as insulators. Insulators have high resistance to the flow of electricity due to their molecular structure, which makes them unable to conduct electricity efficiently. Examples of insulators include rubber, plastic, and glass.
Is pumice porous or non porous?
All natural store is porous and needs to be sealed. Travertine is the most porous over marble and granite
