Yes. Out of paper, plastic, glass, a thermos, a mug, and Styrofoam, the mug held the least heat in. The thermos is the best.
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.
some good insulators are glass styrofoam and almost anything that does not conduct heat very well
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
Insulator are bad conductors of heat and electric current. They do not have the property of transferring heat and electricity from one point to another.
Cloth is a bad conductors/good insulator of heat. Bad conductors keep things warm or cold, so the answer is, because cloth is a bad conductor of heat!
An insulator is something that keeps heat in, for example, if you put a piece of fake fur around a mug of Hot Chocolate, it would act as an insulator, and would keep the heat in the mug. x if u eant insulator..then it means a poor heat conducto, or poor conductor of electricity ----------------------------------------------------------------------------------------------------------------------------------------------------- Materials that do not easily give up or take on electrons are called insulators.
an insulator
A good insulator is good at stopping heat escaping, whereas a bad insulator is not very good at trapping heat and lets it out.
well, i think both would be correct, though a "bad conductor of heat" would be better. Or you could say "insulator for heat" or simply insulator....
In general, metal or anything else that conducts heat or electricity well is a bad insulator.

To maintain the hotness of your coffee, use a plastic mug which is a good insulator, hence minimizes heat loss.
Definitely an electrical insulator. Glass does not conduct electricity. It can be a thermal insulator, but not a great one. You windows on a cold day are pretty cold. Hot coffee in a mug will get the mug warm.
Black because it absorbs all the heat whereas white reflects the heat away so black is a better heat insulator. Help this helps :)
Aluminum will conduct both electric current and heat, so it would be a bad insulator of either.
