Frequent question: What is not a good conductor of heat and electricity?

Metals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat. … These include copper (92), iron (11), water (0.12), and wood (0.03).

Which is the not a good conductor of heat?

Wood, leads, non metal are not good conductor of heat.

Which metal is not good conductor of heat and electricity?

Lead is a poor conductor of heat because it readily reacts with the atmosphere to form lead oxide, where we know metal oxides are poor conductors of heat and electricity as well. Hence, the correct option is (A), Lead.

What are not good conductors of electricity?

Non-metals are generally bad conductors or insulators. Metals, on the other hand, are good conductors. Some other examples of poor conductors of electricity are mica, paper, wood, glass, rubber, Teflon, etc. Some examples of poor conductors of heat are air, lead, etc.

Which of the following is not a conductor electricity *?
