Why is it important to classify matter into conductors and insulators?
If you didn't know the difference, you might try to wire your house with optical fiber.
How can you tell if an object is an insulator?
Different combinations of elements form different types of bonds. Ionic or covalent bonds in solid materials result in materials that have low electrical conductivity (hence are good insulators). Metallic bonds are the kind that produce high conductivity. Liquids may be electrically conductive to the extent that they contain dissociated ions. Liquids that are non polar and contain no ions will be good insulators.
Are stones conductors or insulators?
Generally not; but stone is not an accurate term here - which stone ?
Which material will let heat through?
Thermal conductors let heat through. These tend to be metals, such as aluminium or iron. Bad conductors might be plastic or glass.
What are good conductors that you might find at a typical barbecue?
any metal at a bbq is a conducter along with water

Is plastic a condoctor?
The term plastic has a broad definition as regards materials. There are thousands of plastics. We often think of plastics as organic polymers, and we will generally find that these materials are not good conductors. Different substances added to plastics during production can change this, but we usually find that plastics do not support current flow, and, therefore, might best be considered insulators rather than conductors.
Which matter is the conducter of electric but insulater of heat?
Normally, materials which are good conductors of electricity are also good conductors of heat. This is because both electrical conductivity and heat conductivity is enhanced by mobile electrons, thus making metals both good electrical conductors and good heat conductors. However, I do not know if there might be an exception...
Are scissors conductors or insulators?
Depends on what they're made of, not what they are.Anything made of a conducting material is a conductor, whatever it is.Anything made of an insulating material is an insulator, whatever it is.Material properties - conducting or insulating - is more important than shape.Scissors are generally - but not always - made of metal.And metals are usually conductors, making the scissors conductors.But a scissor might have plastic handles. Plastic is usually an insulator, which would make the handles insulators.
Is nonmetal a good conductors of electricity?
Graphite. You might have come across experiments using a pencil to complete a simple circuit to check if a bulb glows and you might have observed that it does. The graphite in the lead of the pencil is what helps conduct electricity.
What might happen if the electrical cables were installed tightly with no slack?
If you don't allow the conductors to sag then, when they contract in cooler weather, they could (a) snap, (b) break their insulators, (c) pull poles over, or (d) pull intermediate poles out of the ground.
Why to choose Best Lightning Arrestor?
Your question is rather unclear. If you are asking what a lightning arrester is used for, then it provides a means of limiting any overvoltage an overhead line might be subject to due, for example, to a lightning strike. Lightning arresters are connected between individual line conductors and earth (ground). For normal line-to-earth voltages they act as insulators, but their insulating property breaks down when a particular level of overvoltage is reached, and they act as conductors. This limits the value that the overvoltage can reach and, so, the line's insulators are protected.

Does electricity conduct best through aluminum copper rubber or dough?
That depends on the ingredients of the dough. Copper is the second best conducting metal at room temperature. Aluminum has about 59% of the conductivity of copper. Rubber is a generic terms used to describe about 200 different formulas of natural or synthetic pliable substances, most of which are generally insulators (non-conductors or resistive conductors of electricity). The conductivity of dough will depend heavily on the salt, electrolytic, or ionic content of the final product. Dough with a high salt, electrolytic, or ionic content might actually be a better conductor than copper. The problem here is that the heat conductivity of organic components such as are used to make dough is poor--that is they catch fire easily. That's why we don't make wires out of dough.
Why are conductors insulated?
Conductors are insulated to prevent the escape of energy from within them. Without insulators, the conductors will usually release energy into the surrounding substance, unless that substance acts as an insulator. This answer is the result of recollection of a KS3 (high school) science class, and, although quite vague, it is a good outline. It will be useful to search "conductors and insulators" in a search engine, as there will be much more information provided.
