A vacuum is a great sound insulator. Materials that absorb energy such as wool are good insulators as well. I heard of a silicone adhesive that transformed acoustic energies into heat - that was a good insulator if it was used to glue two sheets of something together.
A good insulator is good at stopping heat escaping, whereas a bad insulator is not very good at trapping heat and lets it out.
Yes, air is a good insulator.Yes, air is a good insulator of both heat and electricity
insulator
wool holds lot of air.air being bad conductor of heat make the wool a good conductor of heat.
Sponge is not a good heat insulator as it is porous and can easily transfer heat. Materials like cork or fiberglass are better heat insulators due to their low thermal conductivity.
a good insulator of heat keeps the heat in, so you stay warm

insulator is a object that is not a good conductorSo it keeps the heat in.
Nitrogen is not a good insulator of heat. It is a poor conductor of heat, but it is not an effective insulator as it does not trap heat well and can easily transfer heat through convection or conduction.
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator

No, zinc is not a good insulator. It is actually a good conductor of electricity and heat.
No because it is a good conductor of heat and electricity!
it is a good insulator because its a warm and keeps heat in by trapping it with air
No. Aluminum is a very good conductor of heat.
