* Low density: Gas molecules are far apart compared to solids and liquids. This means there are fewer collisions between molecules, which are necessary for heat transfer.

* Weak intermolecular forces: The weak forces between gas molecules prevent them from effectively transferring energy from one to another.

Instead of conduction, gases primarily transfer heat through:

* Convection: Heat transfer by the movement of heated gas molecules, which rise and displace cooler gas molecules.

* Radiation: Heat transfer through electromagnetic waves, which can travel through a vacuum (like space).

Therefore, while gases can still transfer heat, they are not good conductors.
