Question

gases are poor conductors of heat and electricity

Answer 1

because in gasses, atoms are loosely packed and so, it is impossible to transfer heat and current from one sri to another

Answer 2

They must be reasonably physically close to one another. Because the density of a gas is so much lower than that of a solid or liquid, it will not conduct heat well. The conductance of electricity also requires a high density, but more importantly, since electricity is the flow of electrons, it requires that only minimal energy be required to excite electrons from the valence band to the conductance band. In metals, this band gap is extremely small, allowing large numbers of electrons to be excited to the conductance band by relatively little energy

this is your answer
