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.
No, polystyrene is an insulator, not a conductor. It does not readily allow the flow of electricity through it.
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.
The word "insulators" functions as a noun. It refers to materials or substances that do not conduct electricity or heat effectively.
Insulators: rubber, plastic, glass. Conductors: copper, aluminum, gold.
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.)
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.
No, polystyrene is an insulator, not a conductor. It does not readily allow the flow of electricity through it.
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
There are two types porous and non porous. You can also seel porous concrete to make it non porous.

insulators
Silk is porous -- it absorbs liquids.
Metal is not porous. Many other elements are porous though and when metal combines with them it can potentially become porous.
more porous
The story proved to be quite porous. Lava is a porous rock.
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.
All natural store is porous and needs to be sealed. Travertine is the most porous over marble and granite
