Probably their density. Like cast iron, they are generally fairly thick and
hold heat well.
FriPilot
Diode is a semiconductor material. so it act as insulator also.
Yes, because it has lots of trapped air in it and that's what makes a good insulator.
If the toothpick is made of wood or plastic, it would act as an insulator.
mechanics that act as an insulator or condutor
Alcohol acts as an insulator because it can't freeze and its ability to absorb energy.
Mercury is a conductor of electricity. It is a metal with high electrical conductivity, so it does not act as an insulator.
Metals are conductors, not insulators. Both electrical and thermal conductors.
Hiding
a insulator
It doesn't, it is a conductor of heat and electricity.
Yes, a material can act as both a conductor and an insulator depending on the circumstances. For example, a material like silicon can act as a conductor if doped with certain impurities, but can also act as an insulator in its pure form.
A coat can act as an insulator by trapping heat close to the body and preventing it from escaping, thus helping to keep the wearer warm.
