Want this question answered?
In insulators the bond energy between atoms in the material they form is very high. We need to give large energy to overcome that bond energy and set free the electrons. As electrons are not freely available It doesnt conduct well. There's a kind of circularity in the question. Anything that doesn't conduct electricity for any reason is called an insulator. So any substance where the electrons are too tightly bound to atoms and cannot migrate is called an insulator. Anything that manages to let electrons migrate wouldn't be called an insulator.
Conductor
direct current
thickness doesnt affect it. The higher the density of the material, the greater the speed of sound. e.g 330 m/s in air 1500 m/s in water 4500 m/s in solids
it doesnt work, it breaks it doesnt work, it breaks it doesnt work, it breaks
Bakelite.
it doesnt

no it doesnt because chlorine is a non metal so it wont conduct an sort of commnicatio especially electriciaty.
Heat insulation is defined as the resistance to the flow of heat offered by a material when it is subject to a change in temperature. Objects that put up a lot of resistance to heat flow don't conduct heat well, and are called insulators. Some examples of insulators are wood, rubber and glass. Things that do conduct heat well don't offer much resistance to heat flow. Many metals fall into this category, such as aluminum, copper, and gold. See the link below for more information on heat conduction.
no it doesnt i try to do that in my class so the answer is no.
photosenstive material for holograohic memory doesnt exist...............

Conductor
so it doesnt break
Sodium is a metal having free electrons; solid sodium chloride is not an electrolyte.
because metal doesn't conduct a static current as well as every thing else
