What is the poorest and best conductor?
The best heat conductor is helium II. The poorest heat conductors are perlite and silica aerogel.
Which is the poorest conductor of heat?
water
Is lead a cconductor or insulator of heat?
Like all metals, a conductor, but not as good a conductor as, for example, silver or copper.
Is a lead of a pencil conductor or insulator.?
No. Lead is a realtively good conductor. The insulator is the wood on the outside of the lead.
Is ceramic a bad conductor of heat?
Why is glass a good conductor of heat and ceramic is not a good conductor of heat?
What is the poorest and best conductor?

Which is the poorest conductor of heat?
water
Which material has the poorest conductor of heat?
Glass
What metal is the poorest conductor of heat?
Vacuum
What is the Poorest conductor of electricity tin zinc lead aluminum?
plumbum is poorest
Is lead a good conductor of heat?
maybe..
Is a poor conductor of heat?
Most metals are good conductors of heat, but lead and stainless steel are exceptions. Air is a poor conductor of heat as are fibrous or layered materials. Cloth made from cotton or asbestos or sisal would be poor conductors. Mica would be an example of a layered material that is poor. In most thermal insulators, all you are buying is still air, because still air is (almost) the poorest conductor of heat among the simple materials. Hence the construction of most thermal insulators.
Is lead conductor?
Lead has high resistivity of current. So , lead is not conduct current. But lead has low resistivity of heat and it conduct heat..
Which type of metal is the poorest conductor?
not gold
Is lead a cconductor or insulator of heat?
Like all metals, a conductor, but not as good a conductor as, for example, silver or copper.
A good heat conductor is a?
Copper, aluminum, gold, iron, silver, lead, tin, platinum, nickel, tungsten A and example of a good conductor of heat is a metal.
Why is lead a poor conductor of electricity but a good conductor of heat?
The reason for this is that lead readily reacts with the atmospheric oxygen to forms lead oxide. Lead oxide that has been formed does not have any free electrons. Therefore, it is not able to pass electricity. As, lead exists in the form of lead oxide in which, free electrons are not available.
