Yes. Out of paper, plastic, glass, a thermos, a mug, and Styrofoam, the mug held the least heat in. The thermos is the best.
Yes, a mug is an insulator because it is made of materials that do not conduct electricity or heat well. This is why mugs are used to hold hot or cold beverages without transferring too much heat to your hands.
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
Aluminum is a poor insulator because it is a good conductor of heat and electricity. Due to its high thermal conductivity, aluminum allows heat to easily flow through it, making it ineffective at preventing heat transfer. This property makes it unsuitable for applications where insulation is needed to retain heat or prevent heat loss.
Metal is a good conductor of heat, so when hot water is placed in a metal mug, the heat is quickly transferred from the water to the mug and then to the surrounding air. This rapid heat transfer accelerates the cooling process of the water.
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.

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.
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 :)
