Question

Why gases are poor conductors of heat and electricity?

Answer 1

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

Answer 2

hi,

it's simple.

Because Gases have negligible chemical bonds, so hard for heat and electricity to flow through.
