Stone is most definitely not a good thermal insulator. It changes its temperature quickly with the surrounding environment. In fact, stone is a thermal conductor and will pass heat or cold right to the adjacent materials.
Answer 1Copper [CU] is NOT A GOOD INSULATOR. On the contrary, it is a very excellent conductor of both electricity AND heat! Answer 2Glass, some kinds of rubber, most plastics, vinyl. Most materials are SOMEWHAT conductive and act differently at different temperatures. PURE glass is one of the best insulators. Answer 3If copper was to be a bad conductor..then copper vessels and cables wodn exist,,it s a very good conuctorof heat and electricity

Mica has such poor electrical conductivity that it has often been used as an insulator. The resistivity of mica ranges from 1x10^12 to 2x10^14 Ω/cm depending on the type of mica. For reference, copper, a good conductor, has a resistivity of only 1.68×10^−8 Ω/m or 1.68x10^-10 Ω/cm. no, it is an insulator.
good
no.
Styrofoam is a very porous material; air from the closed pores has a bad thermal conductivity.
with so many other things out there to use as an insulator it would seem a very bad choice, but yes it would bea good insultor, electricity will not flow through it.
A good insulator is good at stopping heat escaping, whereas a bad insulator is not very good at trapping heat and lets it out.
A good insulator means a bad conductor. It is the opposite of good conductor.
Sulfur is a nonmetal. Nonmetals are bad conductors, while metals are good conductors. Since sulfur is a bad conductors, it is a good insulator.
Sulfur is a nonmetal. Nonmetals are bad conductors, while metals are good conductors. Since sulfur is a bad conductors, it is a good insulator.
some good insulators are glass styrofoam and almost anything that does not conduct heat very well
Yes ceramic is a good thermal insulator being bad conductor of heat. For this reason it is being used in the furnaces to contain high temperature.
No. Ceramic is a bad conductor of heat and electricity.
No, thermal energy is just heat. it is good.... like lemons
wool holds lot of air.air being bad conductor of heat make the wool a good conductor of heat.
No shared electrons between neighboring atoms/molecules in the material makes for a good electric insulator.A good thermal insulator has lots of air or gas (which insulates) trapped in the material.
