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 *?
The correct answer is Distilled water. Distilled water is a pure form of water that does not contain ions. Therefore, it does not conduct electricity.
Which is not a bad conductor of heat?
The correct answer is Iron.
Which of the following is a good conductor of electricity?
Graphite is the only non-metal which is a good conductor of electricity.
Is lime juice not a conductor of electricity?
(d) lime juice. Petrol is a hydrocarbon; therefore, it does not have free electrons or ions to conduct electricity.
Is petrol a good conductor of electricity?
The typical value of the electrical conductivity of petrol is 25 pSm–1 . This is very low for petrol to conduct. So petrol is a poor conductor of electricity.
