Is wood a thermal conductor?
Wood is a thermal insulator. It is a poor conductor of heat.
Two identical pieces of ice, each placed on identically sized and shaped blocks of plastic and wood at the same temperature, will melt at a rate proportional to the thermal conductivity and the thermal mass of the object they are on. Generally, plastic is a better thermal conductor than wood. Short answer: wood.
No, it is not. The best thermal conductor among the metals is silver, and it is the best electrical conductor as well. There is a general "rule" in the natural world that thermal and electrical conductivity are proportionate among metals; they "track" together. If a metal is a better thermal conductor than another metal, it will be a better electrical conductor as well. It should be noted that the best thermal conductor of all known…
