All gases are very poor thermal conductors
Graphene is the best thermal conductor. Any metal or metallic objects such as a frying pan would be a good thermal conductor, including diamond.
Helium II (liquid helium) is the best thermal conductor, followed by Graphene, in decending order then , carbon nano-tube, diamond , silver , copper, gold.... see wiki list of thermal conductivities for more information. Interesting to note that water conducts heat roughly 25 times better than air.
The best heat conductor is helium II. The poorest heat conductors are perlite and silica aerogel.
With a thermal conductivity of 237 W/m.K aluminium is a good conductor of heat.
The thermal conductivity of a perfect conductor is 1
The best conductor of electricity is Silver, while the best conductor heat is helium (in its Helium II state), but some people consider diamond as the best heat conductor.

It's not, there are materials that are better, like diamond.

helium is an insulator (poor conductor) of heat
Helium is not a good conductor of electricity since its valence band is full and there is a large gap between this and its conduction band which means that electrons cannot be readily promoted from the fermi level to the conduction band...hence electrons are not free to move and there is no conduction.
With a thermal conductivity of 237 W/m.K aluminium is a good conductor of heat.
helium is an insulator (poor conductor) of heat
Wood is a thermal insulator. It is a poor conductor of heat.
The thermal conductivity of a perfect conductor is 1
Yes, silver is just about the best conductor there is
