Insulation is keeping the hot material hot and vice versa. There is no one best insulator but many. Blanket is one example of a good insulator that keeps you warm.
Metals like sodium (Na) are the best conductors.
Silicon (Si) is a semiconductor---somewhere in between a metal and a non-metal.
Carbon (C) is a non-metal, and in theory would be considered an insulator as most nonmetals are. However, graphite can conduct electricity and so can carbon nanotubes. These are exceptions to the general rule that nonmetals are insulators because of their special structures.
So C should be your answer, but it is an iffy question to begin with. Easier if the non-metal was something like sulfur.this is he correct answer
Si.
Friction involves two substances rubbing against each other. As this happens, one substance may lose electrons, thus becoming positively charged. Consequently, the other substance gains these electrons, becoming negatively charged.
switch...this break the flow of electricity, from a circuit
You could call them a "knowledge seeker" or "curious individual."
Substances that allow heat to travel through them are called conductors; they are usually metals and are used in cooking to make use of their property. Other items, which do not conduct the heat, are called insulators.
Dichotomous key
Aluminum will conduct both electric current and heat, so it would be a bad insulator of either.
Copper - best conductor Glass - moderate insulator Rubber - good insulator
The poorest insulator would be the best conductor, which is one of the noble metals. Bakelite is a fairly good insulator, not too long ago electrical fittings were made from it.
Many - rubber, plastic, ceramics, glass.
The best insulator is likely C because it is a nonmetal. Nonmetals are poor conductors and therefore good insulators. Si is a metalloid.
oxygen.is the best insulator
An insulator has several different meanings. The two most common are an electrical insulator and a thermal insulator. an electrical insulator would be polyethylene. a thermal insulator would be wool.
An example of a good insulator of electricity would be rubber. An insulator is anything that does not conduct electricity and as such offers protection from direct electric current.
A nonmetal would make a good insulator.
it depends what type of insulator youre talking about. wood is a good thermal insulator and rubber is a good electrical insulator A perfect vacuum is the best insulator.
no!!!
If I had to choose the best insulator out of steel wool, aluminum foil, cotton and bubble wrap, I would choose the aluminum foil.
