Is air bad conductor of heat
WebHeat transfer by conduction requires strong bonds between the molecules, so that a vibration (heat) travels down the line. With liquids, this does not happen so easily since the intermolecular forces are weak. Oil should still be able to conduct heat, though, since the "arms" you see "lock" with other molecules.
