Question

different between good and bad conductors of heat

Answer 1

Good Conductor :These are the materials which offers very low resistance to the flow (or in path of) of electric Current.

In other words these materials have very low resistivity.

E.g of good Conductor :silver, copper, aluminum, gold etc.

Bad Conductor :These are the materials which offers very high resistance to the flow(or in path) of electric Current.

In other words these materials have very high resistivity.

E.g. :paper, Mica, glass, teflon

Answer 2

Good conductor -

Those substance through which heat can pass or flow are called good conductor of heat.
Ex. Iron, silver etc.
Human body is good conductor of heat.

Bad conductor or Insulators

Those substance through which heat can not pass or flow are called bad conductor of heat.
Ex. Plastic, wood, paper etc.

Metals are good conductors of heatbut non-metals and gases are usually poor conductors of heat. Poor conductors of heat are called insulators.

Hope you helpful.

If yes then mark me as brainliest.
