Because heat is electromagnetic radiation in the infrared region, therefore, it is emitted and absorbed by charged particles. Since there are mainly two kinds of charged particles; protons and electrons, the electrons are the ones involved in the outer part of an atom, and they either emit or absorb the electromagnetic radiation. This is a transfer of energy, which is synonymous with the transfer of electrons.
Yes , plastic is a poor conductor of heat!!:) Metal is a good conductor though
The statement ' a good insulator is a poor conductor' is false because a good insulator will not conduct at all.
The foam contains air, which is a poor conductor of heat.
No
Polystyrene is a poor conductor of heat; it is largely used as a thermal insulator.
helium is an insulator (poor conductor) of heat
helium is an insulator (poor conductor) of heat
Leaf is a conductor
All of them, a poor conductor does not allow heat to pass through easily, hence any heat inside a box made of a poor conductor would tend to stay there, hence it is an insulator.

It really depends. Glass, for example, does a fair job at conducting heat, but it is an insulator to electricity, which is why it is usually used for the insulators on power lines. Metal, on the other hand, is usually a conductor of electricity, and a conductor of heat as well, so it depends.
A Poor Conductor of heat is usually called an insulator.

No
Wood is not a conductor for electricity. IT is actually a good insulator.
Wood is a thermal insulator. It is a poor conductor of heat.
