Question

What is the best conductor of heat and electricity? what is the poorest conductor of heat and elecricity?

Answer 1

silver, copper, gold, aluminum, are best conuucter of electricity.ike mercury, lead, alloys of iron and chromium, titanium and stainless steel are poor conductors when compared to silver, copper and gold.                                    Examples of poor heat conductors include air, wood, paper, cloth and water.
The best conductor of heat is diamond with a thermal conductivity of more than 2,000 watts per meter per degree Kelvin at room temperature. Silver is the material with the second-highest thermal conductivity at 429 watts per meter per degree Kelvin. This makes silver the metal with the highest conductivity.

Answer 2

Answer:

good conductors - metal, aluminium, copper.... etc.

Poorest conductor of heat and electricity is lead...
