That is called an insulator.
non metals has no luster and is a poor conductor
dry wood
An insulating material such as rubber.
A gas is usually a poor conductor of electricity. In contrast, a brittle solid material that is a poor conductor of electricity is typically an insulator.
An insulator.
Not necessarily. A material could be a poor conductor but a good insulator, depending on how well it can trap and slow down the movement of heat or electricity. It's possible for a material to have low conductivity but still be effective at blocking the transfer of energy.
mica is a plastice, so it is a poor conductor of heat and electricity. Mica is a mineral, not a plastic. But you're correct about its insulating properties.
It is a poor conductor.
Because it is a poor conductor of heat
No, a material with high resistivity is a poor conductor. Resistivity is a property that quantifies how much a material resists the flow of electric current. Materials with high resistivity impede the flow of current, making them poor conductors.
It is a poor material because it is very brittle. This is caused by its high carbon content. It is a poor material because it is very brittle. This is caused by its high carbon content.
helium is an insulator (poor conductor) of heat
