Want this question answered?
electricity
metals have the ability to pass and conduct electricity and heat through them....
No electricity
insulators...
Insulation is keeping the heat inside, trapping it and not letting out. Conduction is letting a flow, such as electricity, pass through the material. for example, metal is a wonderful conductor of heat and electricity, but a bad insulator. However, wool is a good insulator and a bad conductor. :) hope that helps!
Insulators are materials that don't conduct heat well, or (for electricity), materials that don't let electricity pass through them. In general they are non-metallic materials.
wood i think
conduction of heat is when lets the flow of electricity run through. Two good conductors are water and metal. Like when a metal spoon gets hot when you put it in soup. but plastic does not do that
Thermal insulators don't.
Conductor Some materials are conductors of Heat OR Electricity. But the property is not the same for one material; example glass is a good conductor of heat but a poor conductor of electricity.
It is called conductivity
wood is an insulator of heat because its electrons don't allow heat and electricity to flow through them
