World's Worst Insulator?

Want us to do your homework? Get acsuainted with Mr. <Google.com> and enter "Thermal Conductivity!"

OR is it that you are too lazy?

Do nothing simply if you can make it complex and wonderful!

Worst Insulator? No insulation.

But maybe u should be looking for best conductor. That will be the worst insulator.

Or are you looking for something that will causeheat reduction in the shortest time? Thenyou are looking at the geometry of the object rather then insulation property. Please feel free to e-maill me for further info. sam68john@yahoo.com

LOL. Is your school work project, to make sense out of materials descriptions and claims being made by vendors or contractors who would sell products or offer services to upgrade the insulation of your domecile? To help you make the choice before "turning in" your "home" work?

First of all, please excuse me for the other people in this forum that decided better to insult you than help you, (You all could use a nice slap) Secondly, please specify wether you are looking for a Conductor of heat or something that you may call an insulator. with what I am given by the current question, I would be inclined to say aluminum, as this is what you would want to make a heat pipe or a heatsink out of, note how an aluminum engine block in a more recent car will return to ambient far far quicker than one of the older cast-iron ones. I hope that this helps you,

Sincerely

Thomas

Thanks for the sour apples on behalf of one and all who are exasperated with "Guests" who hide in anonymity to pose trick questions. You are overly naive (Charitable?) to think otherwise.

Worst insulator? Equates to best conductor! Of course the table linked to in #2 shows "Ag," i.e. silver as 1.0, the maximum.

The self styled "Guest was "Winding Us Up."

World's worst insulator=world's best conductor.

Be it thermal ,electrical, or whatever. And it doesn't even make a difference where the world.

Wangito.

Look up diamond. Economically, its probably on the low end also.

Silver iz the best natural conductor uv heat (& electricity by the way), thus the worst insulator. Get yourself a copy uv the periodic table uv elements. Also, the book 'The Elements' by John Emsley givez an excellent 'most to least' rundown on many characteristics.

Hope this helps.

Ref: http://en.wikipedia.org/wiki/Electrical_resistivity

diamond is the worst insulator in respect to thermal conductivity

Interestingly, only a few people actually read that the question was regarding the insulator with the worst thermal conductivity (most thermally conductive element) that was also common (enough to bring to class?). I don't know where people are reading resistivity into it. Still my answer still stands - google "thermal conductivity tables". Then find something on the list you have easy access to.

Surprise your teacher by bringing an aluminium engine block to class (the answer will be wrong, but it would still be worth it).
