Is cardboard a insulator or conductor?
Cardboard is an insulator in dry state.But when it is wet it can conduct electricity
Is cardboard a poor conductor of heat and why?
Cardboard is composed of cellulose a polymer that has no free electrons. Without free electrons materials can neither conduct electricity or heat efficiently. If you are referring to corrugated cardboard it is an even better heat insulator because the corrugations capture and immobilize air which almost completely prevents the movement of heat.
Why is cardboard a bad insulator?
The problem with using cardboard as an insulator is that it is too easily damaged in a variety of ways. It tears easily, it can be set on fire relatively easily, it absorbs water very easily and it will disintegrate or become moldy, if it does get wet. So although cardboard is an insulator, it is not durable enough for most purposes that require an insulator.
Is cardboard a thermal insulator?
yes
Is cardboard a better insulator than styrofoam?
No, it's not
Is a oven an example of an insulator?
Uh...No. And neither is a toaster. An insulator is something like cardboard or reflective foil, it keeps the heat in and the cold out :)
Why does ice cream take a longer time to melt in a cardboard box than a metal box?
Metal is a conductor of heat, while cardboard is an insulator. The metal box will heat up quickly, while the cardboard box will be resistant to heat change.

What type of paper is the best insulator of heat?
Don't know if it is the best but Newspaper is a very good insulator and generally easy and cheap or free to get. Cardboard is alo very good.
Is cardboard a thermal insulator?
yes
Is cardboard a better insulator than styrofoam?
No, it's not
Why is corrugated cardboard a good insulator?
Yes! It is a good insulator. I have used it recently in a science project.
Does cardboard absorb heat?
Yes, because it is made of wood, which is a conductor, and also because it can burn.--Actually, cardboard is a very poor heat conductor (but very flammable). Good heat conductors retain heat after the heat source has stopped.
Is potato an insulator of heat?
a potato is not an heat insulator because it's skin,but if you take the skin off it will be a heat insulator
